Varying Gas Pressure Effect on Connecting Rod
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
The automotive industries in recent years are growing with a faster rate with an emphasis on the development of quieter engines to minimize noise and vibration. Hence by improving performance, contribution can be done to minimize the noise pollution. In present work the study of engine part, viz. piston is considered as main source of vibration and noise due to slap. The motion of piston in cylinder from TDC to BDC is of two types, primary motion and secondary motion. The CR top end is connected to piston pin and bottom end is connected to crank shaft, where the gas pressure effect will takes place. By using varying gas pressure it is possible to study the strress developed at the crank shaft contact surface. At different crank angle position the variation of stress developed wil be obtained in crank shaft. The pressure Vs crank angle curve will be compared with stress Vs crank angle graph. The gas pressure curve is obtained from the actual engine performance data of Kirloskar make. In this work the finite element model of the CR is developed and structural analysis is done in ANSYS11 software.
