Material and Cost Optimization of Piston and Piston Ring of Heavy Duty Vehicles Using Finite Element Analysis

MECHANICAL ENGINEERING

In this Research paper J.P. Diesel Company manufacturing Piston facing problem of ceasing of piston due low heat dissipation and failure due to High combustion pressure. Hence as a first step design modification is done by providing four ribs and two ribs for a multi cylinder four stroke diesel engine using CREO parametric 3.0 software. After modification in design Static Structural and Steady state thermal analysis is done using ANSYS software, as per analysis results we can successfully reduced the stress and improve heat flux and factor of safety. In next step three different materials have been selected for structural and thermal analysis of piston and piston ring, structural and thermal analysis is performed using ANSYS software for existing material and modified design-1 and modified design-2 for three different aluminium materials. Result of structural and thermal analysis for different designs and materials is compared with existing design & material of piston and piston ring. Most suitable material for piston and piston ring will be selected to optimize the existing design of piston. For material cost optimization the masses of different material are noted and calculated and compared of existing material and for optimized material.
