Design and Analysis of Four Stroke Six Cylinder Diesel Engine Crankshaft with Geometric Optimization

Crankshaft is a component in an engine which converts the reciprocating motion of the piston to the rotary motion. The aim of this project is to provide efficient model of crank shaft within minute changes in geometry for reducing weight. The less weighted crankshaft improves the mechanical efficiency and power output of engine and also reduces the production costs. Initially data collection and literature survey will be done to understand methodology and selection of material. 3D model will be prepared according to the dimensions' obtained from theoretical calculations. Analysis will be done to validate static structural and dynamic results; geometric modifications will be done according to the obtained results to improve the structural stability, material will be removed where stress is not affected to reduce the weight, The material was changed for modified model for further reducing of weight. Analysis will be done to compare modified with existing model, conclusion will be made according to the obtained results
