Electric Power Generation from Road Humps

Energy serves as the fundamental element crucial for the survival of all life forms across the vastness of the universe. It acts as the cohesive force directing various processes shaping our environment. However, this delicate equilibrium is endangered by the depletion of traditional energy sources, worsened by the ever-growing global population. This dilemma leads to an imminent energy crisis expected to arise in the next five years due to excessive consumption. To navigate this challenging situation, there's a need for a significant shift in approach, urging the adoption of methods to maximize the use of existing energy sources. In our research, there's a promising opportunity to tap into kinetic energy, particularly from vehicles traversing over speed bumps. The proposal suggests converting these ordinary road features into dynamic generators, seamlessly transforming kinetic energy into electricity for the grid. This process involves sophisticated mechanisms like rack and pinion systems to efficiently convert kinetic energy into mechanical power, eventually generating electricity for storage and later use. This innovative solution not only addresses energy conservation but also promises economic benefits, utilizing stored energy to power street lights during the night, and enhancing urban landscapes with efficient illumination. Key Word: Generator; non-conventional energy source; rack and pinion mechanism; chain sprocket; speed breaker.

Establishment of Chain Library Based on UG

Sprocket chain drive is a common transmission mode in mechanical engineering that is widely used. However,due to the complexity of sprocket chain manufacturing, the three-dimensional design and motion simulation and analysisusing modern engineering software are time-consuming, and a great deal of calculations are needed. Therefore, it is ofgreat significance to develop a sprocket chain reuse library based on the modern engineering software Unigraphics. Amongthem, the sprocket design library was designed many years ago and published relevant papers (establishment of sprocketparametric modeling and reuse library based on UG). Therefore, this time, the chain reuse library is mainly establishedfor sleeve roller chains that meet the national standard (GB/t1243-2006), With the sprocket reuse library, 3D models canbe established and assembled rapidly. The system was proven to be efficient and reliable through numerous engineeringdesign verifications. This system makes engineering design, 3D assembly, and motion simulation easier and provides areference for the development of other complex computing systems.

Design and Development of AKEA: A 360-degree rotating vehicle

The design of a 360-degree rotating vehicle has been proposed as a solution to the problems encountered in traditional wheel vehicles. This paper highlights the benefits of such a design, the proposed models for implementing the design, and the design of a 360-degree rotating vehicle known as AKEA. Traditional wheel vehicles are faced with numerous problems such as parking and u-turn. The 360-degree rotating vehicle design eliminates these problems as it can take turns without moving the vehicle, and no extra space is required to turn the vehicle. The proposed models for implementing the design of the 360-degree rotating vehicle include lifting plates, chain sprockets, chain or belt drives, and quad-steering mechanisms. These models have several shortcomings, including complexity in design, unrealistic features and increased turning radius. The AKEA design, however, incorporates sustainable and recycled materials, and the result of the design process was a vehicle that performed various features. These features include side-ways movement, 360-degree rotation, and mobile phone operation. AKEA is connected to the mobile phone via Bluetooth, having a range of 100 meters. However, to improve the design further, sensors for self-driving and WiFi connectivity for a broader range of connectivity were proposed. In conclusion, the design of a 360-degree rotating vehicle is necessary to reduce and eliminate problems encountered in traditional wheel vehicles. Although several models have been proposed, the AKEA design performs various features and can be implemented in modern cars and trucks. Improving the design by incorporating sensors and WiFi connectivity will improve the responsiveness of the mobile application and ensure wider range connectivity.

Design and Analysis of Internal–External Composite Meshing Hy-Vo Chain

The internal–external composite meshing mechanism should be the best way to improve the transmission performance of a silent chain drive, but there is no internal–external composite meshing Hy-Vo chain under the classical design approach. In this research, by building the Hy-Vo chain meshing system, the difference between the meshing of the chain–sprocket and the meshing of the rack–gear is deeply analyzed. By rigidifying the external meshing Hy-Vo chain as a rack, the fluctuation range of the pitch line of the external meshing Hy-Vo chain is analyzed. Based on the relations between the actual chain pitch line and the rigid chain pitch line, the design method for the internal meshing profile of the internal–external composite meshing Hy-Vo chain is deduced, the necessary conditions are obtained, and the meshing characteristics are analyzed. By conducting comparative multi-body dynamics experiments, the results prove that the design method of the internal–external composite meshing Hy-Vo chain proposed in this study is effective and feasible. The results also show that the description of the internal–external composite meshing in the classical meshing theory is not completely correct. In fact, the internal–external composite meshing mechanism cannot reduce the meshing impact of the Hy-Vo chain system and can only improve the system polygon action, the meshing performance, and the transmission stability.

The sample data was obtained from a sensitivity analysis drive from FEA. The optimum geometry of the motor was directly solved by implementing a multiobjective optimization (MOO) method of genetic algorithm. Finnaly, the optimum geometry of the MOP-ANN based result is validated by FEA.

Effect of Quenching Media on the Strength of AISI 1045 Steel Applied to Chain Sprockets: Impact Test Method

A chain sprocket is a geared wheel attached to a chain, track, or other long geared object made of AISI 1045 steel, which is subjected to friction and pressure in its application. Each steel has different characteristics, such as physical, mechanical, and chemical properties; therefore, it needs a special handling which is expected to have a longer life from the design, then the wear resistance of the material can be done through heat treatment by hardening followed by a quenching process using oil, salt solution and water aimed at increasing resistance to friction and pressure. The results of the impact test on AISI 1045 steel (original) have shown an average of 10.24 joules while the steel by hardening and quenching with various media has proved to show a higher average value, for instance, the AISI 1045 steel by oil, its value is 53.35 joules, by salt solution 69.02 joules, and by water 91.60 joules. Meanwhile, the average impact strength of AISI 1045 steel (original) is 0.128 J/mm2, 0.665 J/mm2 by oil, 0.862 J/mm2 by salt solution, and 1.144 J/mm2 by water.

GAPSO-Optimized Fuzzy PID Controller for Electric-Driven Seeding.

To improve the seeding motor control performance of electric-driven seeding (EDS), a genetic particle swarm optimization (GAPSO)-optimized fuzzy PID control strategy for electric-driven seeding was designed. Since the parameters of the fuzzy controller were difficult to determine, two quantization factors were applied to the input of the fuzzy controller, and three scaling factors were introduced into the output of fuzzy controller. Genetic algorithm (GA) and particle swarm optimization (PSO) were combined into GAPSO by a genetic screening method. GAPSO was introduced to optimize the initial values of the two quantization factors, three scaling factors, and three characteristic functions before updating. The simulation results showed that the maximum overshoot of the GAPSO-based fuzzy PID controller system was 0.071%, settling time was 0.408 s, and steady-state error was 3.0693 × 10−5, which indicated the excellent control performance of the proposed strategy. Results of the field experiment showed that the EDS had better performance than the ground wheel chain sprocket seeding (GCSS). With a seeder operating speed of 6km/h, the average qualified index (Iq) was 95.83%, the average multiple index (Imult) was 1.11%, the average missing index (Imiss) was 3.23%, and the average precision index (Ip) was 14.64%. The research results provide a reference for the parameter tuning mode of the fuzzy PID controller for EDS.

Dynamic Properties of Chain Drive in a Scraper Conveyor under Various Working Conditions

A scraper conveyor is important in coal mining. During operation, its working performance is affected by chain speed fluctuations, terrain fluctuations, and load changes. Thus, evaluating the influence of these factors on the dynamic properties of a scraper conveyor is important. This study first built a dynamic property test bench. Then, the vibration signals of the reducer output shaft were measured under various chain speed, terrain, and load conditions. Finally, the dynamic properties of a scraper conveyor were evaluated by conducting a frequency domain analysis of the measured vibration signals. The results show that the output shaft of the motor, the second shaft, and the second-stage meshing gear of the reducer are sensitive to external factors. Under the terrain conditions of “horizontal + vertical” bending, the middle chute was the most sensitive to the meshing frequency of the sprocket chain. This type of condition had a significant influence on the scraping phenomenon of the scraper and the middle chute. Under various load conditions, the amplitude of each shaft of the reducer decreased, especially the amplitude of the motor output shaft, but the scraping amplitude of the scraper and middle chute greatly increased. This study is of great significance for improving the dynamic properties and structural optimization of scraper conveyors.

​Development and Performance Evaluation of a Two-row Mechanical Paddy Transplanter

Background: Paddy is one of the most important staple food in most south-east Asian countries. It is grown either by direct sowing or by transplanting under wetland conditions depending upon the availability of water. India produces 116.48 million tonnes of rice with a productivity of 2659 kg ha-1. Manual transplanting of rice seedlings by hand is generally done in stooping posture which is laborious and drudgery. It also requires a huge amount of labour during peak season. Considering the need and to suit the hilly region, a two-row manually operated paddy transplanter was developed. Methods: For picking the seedlings, a four-bar mechanism was selected as the basis of design. The machine construction consists of a float, seedling tray, fixed-fork type finger, chain sprocket system and lugged wheel. For operation, the operator has to rotate the crank handle which transmits the motion through the chain sprocket system and four-bar linkage which in turn picks the seedlings and plants them onto the soil. Result: The machine was tested in the actual field condition and was working satisfactorily. The designed fixed fork-type finger can hold 5 to 8 seedlings at a time. The developed machine was found to be comfortable working at a speed of 0.5 kmph. The actual field capacity of the machine was 0.02 ha/h.

Research on buoy–chain–sprocket wave energy capture technology

A high-reliability, low-cost buoy–chain–sprocket wave energy capture device is proposed. Resonance theory is used to improve its wave energy capture efficiency and reduce its cost. The testing principle of the buoy–chain–sprocket model is proposed, and comparable resonant and nonresonant experimental floating body models were constructed based on finite depth linear wave theory and the resonance principle. Then the methods and results of the model experiments are described. Based on using Morison equation to calculate wave load, simulation and verification of the model experiment were conducted by using AQWA and OrcaFlex software. Finally, to eliminate the size effect and the impact of one-way wave energy collection, based on the simulation technology described above, sea-state prototype models of resonant and nonresonant buoy–chain–sprocket wave energy capture devices with one-way and two-way acquisition characteristics were constructed. Simulations were then conducted to get the maximum wave energy gathering efficiency. The research result indicates that the nonresonant buoy–chain–sprocket wave energy capture device with one-way acquisition has higher wave energy capture efficiency than the resonant buoy–chain–sprocket wave energy capture device.
