Warranty Cost Estimation using K-Means Cluster Analysis for Automobile Industry: Technical Note

When a vehicle under warranty comes for service, the technician identifies the potential fault and the corresponding service is done. From the raw information of customer complaint, the complaint codes are identified and allocation of qualified technician involves considerable man hours and cost per hour for the technician to do the service. Around 1059 vehicles under warranty were studied starting from customer complaint to the study of warranty cost to the manufacturer. In this paper, initially, we present the results of classifying the complaint code master into several classes using K-means cluster analysis and subsequently cluster analysis for a specific component say, water pump assembly was carried out. Then, analysis of cost to the automobile manufacturer on warranty claims are also presented here.

Motion Analysis System (MAS) for production and ergonomics assessment in the manufacturing processes

Nowadays the Smart Factories operating within the Industry 4.0 revolution, require more and more reliable, fast and automatic tools for production analysis and improvement. Manufacturing companies, in which the human labour has a crucial role, need instruments able to manage complex production systems in terms of resource utilization, product mix, component allocation and material handling optimization.In this context, this work presents an original hardware/software architecture, Motion Analysis System (MAS), aimed at the human body digitalization and analysis during the execution of manufacturing/assembly tasks within the common industrial workstation. MAS is based on the integration of the Motion Capture (MOCAP) technology with an ad hoc software developed for productive and ergonomic analysis of the operator during his work. MAS hardware integrates a network of depth cameras initially developed for gaming (Microsoft Kinect v2™, conceived for markerless MOCAP) and now used for industrial analysis, while an original software infrastructure is programmed to automatically and quantitatively provide productive information (human task analysis in terms of time execution and used space within the workplace, movements of hands and locations visited by the operator) and ergonomic information (full body analysis implementing all the internationally adopted indexes OWAS, REBA, NIOSH and EAWS). This double perspective makes MAS a unique and valuable tool for industrial managers oriented to the workplace analysis and design (in terms of productivity) without neglecting the operator health. This proposed contribution ends with a real industrial application analysing a water pump assembly station: the system setup is discussed and the key results obtained adopting MAS are presented and analysed.

Design and Experiment Study of High Power Automobile Water Pump Based on CFD

A high power automobile cooling water pump is designed and developed based on the theory of centrifugal pump design and computational fluid dynamics (CFD). The structure of the automobile cooling water pump adopts a curved guide rib structure, so as to avoid the dry friction of the automobile cooling water seal of the pump. The structural elements and flow field of the automobile cooling water pump assembly are optimized by simulation analysis. The peak efficiency of the automobile cooling water pump assembly is more than 51%, the automobile cooling water pump performance has been significantly improved. The effective methods and means of product verification have been developed to ensure the high reliability and durability of the automobile cooling pump assembly.

Corrosion investigation of stainless steel water pump components

Abstract Two components of a water pump installed in a casting shop for recirculation of cooling water experienced severe and accelerated corrosion after two months in service. The received pieces of the water pump assembly were a shaft and a conical tube, which was used as connector with the impeller. The shaft exhibited circumferential pitting corrosion behavior in specific areas where it was in contact with another pump component. Light optical microscopy and Scanning Electron Microscopy coupled with Energy Dispersive X-ray Spectroscopy were mainly used as analytical techniques for corrosion process evaluation and for the identification of the morphology and chemical composition of corrosion products, in order to draw safe conclusions concerning the type of the corrosion and the respective root-source. The main findings of the investigation indicated that pitting corrosion was the dominant failure mechanism for both water pump components influenced by the presence of aggressive environmental conditions, characterized by the presence of chlorides and sulfates that accelerate corrosion process above a certain temperature range (T > 50–55 °C).

Effective Utilization of Industrial Robots—A Job and Skills Analysis Approach

Abstract The comparative abilities and limitations of industrial robots and humans are reviewed. This comparison leads to the development of a robot oriented job and skills analysis method with a two-fold objective: 1) to optimize a robot's task-performance, and 2) to guide the specification of the appropriate robot for given tasks. An example of water pump assembly by a robot is used to illustrate the proposed method and its usefulness.

Laboratory suggestion: a simple modification to extend gasket life and prevent leakage on shaft-driven centrifugal pumps.

A method of placing a small teflon sleeve over the shaft which cuts down friction between the metal shaft and rubber gasket and allows a tighter, more lasting seal is described. Special reference is made to the water pump assembly on the Model 113 and 123 IL Blood Gas Apparatus with the Model 127 constant temperature bath.

Disassembly Sequence Analysis ForEnvironmentally Conscious Design And Manufacturing

Environmentally conscious design and manufacturing (ECDM) is becoming a very important issue in the manufacturing community. Adequate product reuse and recycling can greatly reduce waste generation, thus increasing product environmental compatibility. Design for disassembly analysis is a building block of the ECDM system. It is able to design or redesign products so that a higher percentage of the component parts can be reused or recycled. In this study, an economic model of disassembly analysis is formulated and integrated with an object oriented product model. Due to the nonlinear and combinatorial characteristics of the problem, a simulated annealing algorithm is employed to find the economically optimal sequences that yield the maximum return value, and to advise where the disassembly operation should stop. It shows the potential of analyzing the environmental friendliness of material selection, assembly configuration, and fastening methods. The proposed method is illustrated with a water pump assembly example.
