Desain Lemari untuk Masjid di Kecamatan Cisaat Kabupaten Sukabumi

Cisaat Subdistrict has many mosques that are actively used by the community for various religious and social activities. However, based on an initial survey, it was found that many mosques in this area still lack adequate storage facilities to store various religious items such as Qur'ans, Islamic books, prayer garments (mukena), and sarongs. To address this need, the social service team designed a cabinet using a systematic and structured design method with a minimalist and ergonomic concept. The mosque cabinet design was created using Autodesk Inventor software with dimensions of 800 mm in length, 350 mm in width, and 1200 mm in height. The design for storing sarongs and prayer garments uses a closed concept (drawers), while the design for storing Islamic books and Qur'ans uses an open concept (shelves). Through this social service program, it is expected that an optimal design can be obtained to meet the cabinet needs of mosques in Cisaat Subdistrict, making this design a reference for mosque management committees in creating optimal and functional mosque cabinets.

FINITE ELEMENT ANALYSIS OF A LONGITUDINAL TRANSMISSION SYSTEM

This paper addresses how a longitudinal transmission system of a car could be analyzedusing Autodesk Inventor software. The longitudinal transmission, also known as a driveshaft or cardan shaft, is a system used in rear-wheel-drive or all-wheel-drive vehicles where power is transmitted from the engine to the rear axle or to both axles. During the operation of the longitudinal transmission, various loads can lead to the wear and tear of the universal joints, resulting in failures or even the destruction of the system. To prevent these issues, we considered it necessary to analyze the modelled driveshaft using Inventor based on von Mises stresses and the safety factor. The material used in this study is cast steel with the following properties: Mass Density 7.85 g/cm³, Yield Strength 250 MPa, Ultimate Tensile Strength 300 MPa, and Young's Modulus 210 GPa. The results obtained for different angles of inclination of the universal joint axes lead to the conclusion that the positioning of the driveshaft significantly influences the durability of the longitudinal transmission system.

Development of 3D-printed universal adapter in enhancing retinal imaging accessibility

BackgroundThe revolutionary technology of smartphone-based retinal imaging has been consistently improving over the years. Smartphone-based retinal image acquisition devices are designed to be portable, easy to use, and cost-efficient, which enables eye care to be more widely accessible especially in geographically remote areas. This enables early disease detection for those who are in low- and middle- income population or just in general has very limited access to eye care. This study investigates the limitation of smartphone compatibility of existing smartphone-based retinal image acquisition devices. Additionally, this study aims to propose a universal adapter design that is usable with an existing smartphone-based retinal image acquisition device known as the PanOptic ophthalmoscope. This study also aims to simulate the reliability, validity, and performance overall of the developed prototype.MethodsA literature review has been conducted that identifies the limitation of smartphone compatibility among existing smartphone-based retinal image acquisition devices. Designing and modeling of proposed adapter were performed using the software AutoCAD 3D. For the proposed performance evaluation, finite element analysis (FEA) in the software Autodesk Inventor and 5-point scale method were demonstrated.ResultsPublished studies demonstrate that most of the existing smartphone-based retinal imaging devices have compatibility limited to specific older smartphone models. This highlights the benefit of a universal adapter in broadening the usability of existing smartphone-based retinal image acquisition devices. A functional universal adapter design has been developed that demonstrates its compatibility with a variety of smartphones regardless of the smartphone dimension or the position of the smartphone’s camera lens. The proposed performance evaluation method generates an efficient stress analysis of the proposed adapter design. The end-user survey results show a positive overall performance of the developed universal adapter. However, a significant difference between the expert's views on the developed adapter and the quality of images is observed.ConclusionThe compatibility of existing smartphone-based retinal imaging devices is still mostly limited to specific smartphone models. Besides this, the concept of a universal and suitable adapter for retinal imaging using the PanOptic ophthalmoscope was presented and validated in this paper. This work provides a platform for future development of smartphone-based ophthalmoscope that is universal.

Numerical Simulation and Design of a Mechanical Structure of an Ankle Exoskeleton for Elderly People

This article presents the numerical simulation and design of an ankle exoskeleton oriented to elderly users. For the design, anatomical measurements were taken from a user of this age group to obtain an ergonomic, resistant, and exceptionally reliable mechanical structure. In addition, the design was validated to support a “weight range” of users between 50 and 80 kg in order to evaluate the reaction of the mechanism within the range of loads generated in relation to the first principal stress, the safety coefficient, the Von Mises stress, and principal deformations, for which the 3D CAD software Autodesk Inventor and theoretical correlations were used to calculate the displacement and rotation angles of the ankle in the structure. Likewise, two types of materials were evaluated: ABS (acrylonitrile butadiene styrene) and a polymer reinforced with carbon fiber. Finally, the designed pieces were assembled with the guarantee that the mobility of the system had been validated through the numerical simulation environment, highlighting that by being generated through 3D printing, manufacturing costs are reduced, allowing them to be accessible and ensuring that more people can benefit from this ankle exoskeleton.

Static and Dynamic Analyses of Spindle Collet Made of Different Materials Using Finite Element Modeling

The spindle collet, a critical component in various machine tools, plays a pivotal role in determining the success of machining operations. This paper aims to study the static and dynamic parameters of collet structures made from three different materials using the finite element method. A three-dimensional model and computer simulation were conducted in Autodesk Inventor software. Simulations are performed using identical boundary conditions and mesh size. Static analysis is performed with varied applied forces where total deformation and Von Mises stress are measured. For the dynamic analysis, the natural frequencies and mode shapes are measured up to the first five modes. The variations in stress is minimal when the material is altered. The magnitude of deformation varies significantly with changes in material. The relative deformation values demonstrate that carbon steel deforms more than alloy steel by almost 3%, while stainless steel deforms more than alloy steel by 6%. Materials with higher Young's modulus and lower density have been found to increase the natural frequencies, reducing total deformation and von Misses stress. The use of alloy steel in the industry offers an advantage over the other two materials. The results provide improved insight into the appropriate materials for the collet.

SHAPE'S IMPACT ON DIMENSIONAL PRECISION IN 3D PRINTED COMPONENTS

In this comprehensive exploration, the study explores the relationship between shape and the dimensional accuracy of components manufactured through additive manufacturing processes. The methodology involves the adept utilization of Autodesk Inventor Software, strategically embossing capital letters from A to O onto a rectangular plate. The resulting models are exported in STL format, laying the foundation for rapid prototyping. The investigation unfolds with the application of a Prusa İ3 desktop 3D printer, where specific settings, including layer height (ranging from 90 to 300 microns), 20% infill density, and a heated bed temperature of 60 ºC, are scrupulously chosen. Three different embossing methods are examined in this study in order to see how each affects dimensional correctness. These methods are join, cut half, and cut through. Through a meticulous comparative analysis, facilitated by high-resolution image acquisition and advanced processing techniques like binarizing and edge detection, the study discerns that embossing with join yields shapes characterized by higher dimensional accuracy, a conclusion substantiated by correlation coefficient analysis. This research stands as a significant contribution, offering valuable insights into optimizing additive manufacturing processes and elevating dimensional precision in 3D printed components.

Unmanned aerial vehicle (UAV), also known as drone is one of the most interesting emerging technologies with a wide range of applications including agriculture, surveillance, security, search and rescue, mapping, farmland surveying, and wildlife conservation, among others. In Nigeria, UAV is gaining popularity in applications such as in social functions for taking both moving and static pictures, military and security, mapping and agriculture. In this work, an UAV was designed, some components produced by 3D printing, coupled and tested with certain level of local content in view. The UAV is a quadcopter equipped with a camera for real-time image capture of farmlands and it can perform autonomous missions by using global positioning system (GPS) waypoints. The weight of the quadcopter was approximately calculated and hence the electrical and mechanical components selected using a standard empirical design table. The thrust to weight ratio was set at 2:1. Autodesk Maya and Inventor software were used to design the frame in two parts: the frame arms on which the propellers are mounted and the central connecting part that links the four arms. The arms are made up of aluminum square pipes while the central connecting part for the arms was printed with a 3D printer (200 x 200 x 200 Wanhao duplicator i3) using PolyEthylene Terephthalate Glycol (PETG) Filament material of 1.75mm standard gauge. Material selection was based on material strength, cost and availability. NCH Debut video and image capture software was used to record live feeds from the UAV onboard camera. Functionality tests for lift, stability, yaw, roll, pitch, loiter, auto landing, return to launch, flight time, altitude/signal, auto mission using GPS waypoints were carried out with the completed UAV on a less windy day to avoid the influence of wind. It was generally observed that the UAV successfully took off the ground, gained stability, flew to over 100m height, captured aerial photographs of the land below it while on flight at the required height and landed safely. Cost saving advantage of 45.28% was achieved when compared to imported equivalent types.

Conceptual design and analysis of a tricycle mounted solar-powered photovoltaic cold room system

Energy crisis in developing countries is worrisome, and this has made the preservation and transportation of medical and perishable food items a common problem. Most conventional refrigeration systems operate with electricity; however, there are regions where it is difficult or not cost efficient to provide electric service. Therefore, this research seeks to solve the problems of inconsistent, irregular and complete non availability of power supply required to keep food products and drugs refrigerated over a long period of time by designing a tricycle mounted solar-powered cold room. The tricycle mounted solar-powered cold room designed consists of a refrigeration system having a compressor, a condenser, an expansion valve and an evaporator; a solar system having a photovoltaic (PV) module, charge regulator, storage battery and DC to AC inverter; and a tricycle for easy distribution and safe delivery of refrigerated items. A comprehensive analytical design was performed on each of the systems and the design results showed that the solar-powered cold room has refrigerating cooling load, PV array size, battery cap, and inverter power of 986 W, 275 W, 94 kWh, and 8000 W respectively. A structural analysis was also carried out on the tricycle chassis using the finite element method on Autodesk Inventor software. The results showed that the maximum von misses stress experienced by tricycle chassis was 56.96 MPa which is significantly lower than the yield strength of the chassis material used in the design, indicating a robust structural integrity and can therefore be used to carry the loads that it will be subjected to without deformation.

Компенсатори переміщень тримальних канатів підвісних доріг для транспортування лісоматеріалів

Cableways for timber transportation are quite effective in terms of manufacturability, specific energy consumption, material capacity and the negative impact level on the environment in difficult natural operating conditions, compared to similar types of machines. Since non-stationary cableways are usually used in forestry production, which are characterized by a light construction with relatively small safety margins of cable equipment elements, then for this type of roads, the reliability and safety of the skylines work are important factors for their effective operation. In order to reduce the cost and duration of installation and dismantling operations, the skylines are usually rigidly fixed to trees, stumps or artificial supports. Such a cable fastening scheme is technically convenient, but it does not allow for constant tension of the skylines when the carriage with the load is moving along the span, under wind load, possible temperature fluctuations, icing of structural elements, and emergency situations. As a result, intensive changes in cable tension during their operation cause dynamic loads and vibrations in the cable rigging, as well as uneven and accelerated wear of the skylines, and a decrease in their durability. Under such conditions, in order to increase the reliability of the cable rigging of timber transportation cableways (both individual existing models of equipment and the latest ones), it is proposed to equip them with displacement compensators for the skylines. After analyzing a number of prototype devices that are effectively used in related industries, it was concluded that pneumatic, mechanical, and hydraulic compensator designs can be considered rational for timber production. Therefore, in view of the above, we performed a detailed calculation and designed the main technical elements of the compensating device, developed a control scheme for its working body, and analyzed its stress-strain state using the Autodesk Inventor software package. The use of rational compensator designs and appropriate control schemes for their working bodies will create the prerequisites for reliable and safe operation of timber transportation cableways in various operating modes and terrain and climatic conditions, and minimize the likelihood of emergencies
