This document describes the optimization design and computational fluid dynamics (CFD) thermal analysis of a 72/48 switched reluctance motor (SRM) for a mining application. A multi-objective optimization framework is proposed using surrogate modeling to reduce computational time. Key steps include design of experiments to collect data, sensitivity analysis to reduce design variables, constructing Kriging surrogate models, and using particle swarm optimization on the models. Thermal analysis using CFD is also performed to evaluate different water jacket configurations and reduce motor temperatures. The optimization results are validated using finite element analysis and show the 72/48 SRM is suitable for high-torque low-speed direct-drive in mining.
The document summarizes the optimization of the weight of a C-frame hydraulic power press through finite element analysis using ANSYS and modeling using PRO-E.

The optimized design reduces manufacturing costs without compromising on structural integrity.
Design and analysis of an electric karteSAT Journals
Abstract This paper presents the design and analysis of an electric motor powered kart. The main aim of this paper is to reduce the usage of organic fuel powered vehicles and to design a vehicle which works efficiently in the emerging electric vehicle sector. In order to maintain the speed levels of the kart, seamless decision was made in motor selection. Alternate materials have been applied in the kart to reduce both static and dynamic forces in pursuance of improving the efficiency and performance of the kart. Detailed design of subsystems like chassis frame, steering system, electrical power train and braking mechanism has been done effectively. The main focus of the frame design was on the stability of the kart and safety of the driver. The CAD model of the kart was done in CREO 2.0. Aluminium alloy 6063 has been employed for the frame to reduce the overall weight. To check the feasibility of the frame design, finite element analysis has been done using ANSYS 14.5. The results obtained showed that the frame design was safe under maximal impact load conditions. Weight reduction was a major concern and hence linkage type steering was selected for the kart. Motor, the heart of the electric vehicle was selected and installed in such a way that it can perform well for an extended run time. PMDC motor was selected in this case. Speed control of the kart was done using a voltage controller. The kart is provided with a timing belt drive to achieve maximum efficiency in transmission of power from the motor to the wheels. Hydraulic disc brakes were provided for smooth and effective braking under both dry and wet conditions. Slick tires are used to provide more traction. Design calculations were carried out and optimum results were obtained. An extensive market survey was also done on frame material, brakes, motor, transmission system for cost and availability. International standards were followed throughout the design process. Keywords: Stability, Frame, Finite Element Analysis, PMDC Motor, Timing belt

This document summarizes a case study on the reverse engineering and redesign of a steam turbine blade. The process involved laser scanning the blade to create a 3D model, performing finite element analysis to evaluate stresses, and proposing design upgrades. Two areas analyzed were the tenon, where cracking was found, and the blade attachment, where a fir-tree design was proposed to reduce stresses at crack sites. The redesign incorporated blade modeling, analysis of stresses and frequencies, and verification that the new design met structural requirements for safe operation.
Design evaluation and optimization of steering yoke of an automobileeSAT Journals
Abstract The purpose of a steering system is to control the direction of the vehicle by operating the steering wheel of the steering system. The steering columns in a steering system are one of the main devices of an automobile. It is a very important part to attain stability and steady movement of the vehicle. The steering yoke consists of two forged-steel yokes or forks joined to the two shafts being coupled and situated at right angles to each other. A spider hinges these two yokes together. Since the arms of the spider are at right angles the spider arm rocks backwards and forward between four extreme positions. Motion transmission system of vehicles consist several components which sometimes encounter unfortunate failures. Some common reasons for the failures may be manufacturing, design faults, maintenance faults, raw material faults, material processing faults as well as the user originated faults. In this paper structural optimization of the steering yoke is carried out. For modeling of the component, CATIA V5 R17 software is used. It has been found that there are essentially in two stages of the design process that structural optimization can be applied. In the early stage of concept generation, topology optimization should be used to develop an efficient structure from the beginning. At this level an automatized variation of optimization parameters was proven useful to and the best feasible design possible. In the later stage, shape and size optimization should be used to fine-tune the structure realized from the topology optimization and carried out physical experimentation to validate the model.

The study on effect of torque on piston lateral motion eSAT Journals
Abstract The studies of engine components reveal the cause for the engine vibration and noise. The piston slap due to the impact of the piston in the walls of the cylinder is considered as one of the predominant source of engine noise. In the present work engine performance characteristics are considered. The variation of the torque from minimum to maximum and the corresponding values of the engine performance parameters are logged. The effect of torque on engine speed and on piston movement is studied. The duration of the piston in cylinder for these input values ore also logged. The piston lateral movement is recorded by measuring the gap between cylinder inner wall and the piston skirt for the piston primary motion from TDC to BDC and vice versa. Finite element analysis is carried for von-Mises stress and x-directional displacement for the lateral displacement. The high stress region in the piston is emphasized for the study. It is found that near TDC region the engine is experiencing the maximum impact due to high torque which is the result of combustion pressure and also corresponds to the cause for piston lateral motion in this region.

The study on effect of torque on piston lateral motion eSAT Journals
Abstract The studies of engine components reveal the cause for the engine vibration and noise. The piston slap due to the impact of the piston in the walls of the cylinder is considered as one of the predominant source of engine noise. In the present work engine performance characteristics are considered. The variation of the torque from minimum to maximum and the corresponding values of the engine performance parameters are logged. The effect of torque on engine speed and on piston movement is studied. The duration of the piston in cylinder for these input values ore also logged. The piston lateral movement is recorded by measuring the gap between cylinder inner wall and the piston skirt for the piston primary motion from TDC to BDC and vice versa. Finite element analysis is carried for von-Mises stress and x-directional displacement for the lateral displacement. The high stress region in the piston is emphasized for the study. It is found that near TDC region the engine is experiencing the maximum impact due to high torque which is the result of combustion pressure and also corresponds to the cause for piston lateral motion in this region. Index Terms: engine torque, finite element analysis, lateral motion, and stress
