Increase of Fatigue on Piston and Connecting Rod in Using Supercharger

Abstract:

This research deals with analysis the fatique and the failure of piston engine using FEA.The objective of this research is to develop the geometry of piston engine using solidwork software and to investigate the maximum stress using stress analysis techniques to predict the failure of piston and connecting rod and identify the critical locations of the components of EF7 engine with supercharger and without supercharger. The finite element model of the components was analyzed the static stress with linear material model . first we discuss the amount of increased pressure in cylinder by supercharger and turbocharger then the influence of the inlet air pressure on the naturall aspirated engine which the main parts of its engine are not reinforced is taken account,then the result is showed the stress is increased by quantity of 273 MPA on piston and connecting rod which make the increase of fatigue on pistons and connecting rod and decrease in its period of working.The results can also significantly reduce the cost to produce the piston,and improve product reliability and improve the fatique strength and durability.
