Produktbeschreibung

The motion of the piston and oil in during impact on the cylinder bore commonly known as piston slap. The early theoretical analysis showed that the form of cylinder pressure development determines the dynamic stress in the engine parts. In this study the effect of the piston secondary motion is taken for the analysis considering combustion pressure contributing to the dynamics of the piston. This work is carried out in ANSYS 10 commercial finite element analysis software. To understand the complex behavior of the piston in motion relative to the other engine parts viz., connecting rod, crankshaft, a multi body dynamic (MBD) analysis is carried out. This analysis showed the occurrence of piston tilt near TDC and BDC. The analysis results can effectively be used to optimize piston geometry and hence lateral forces are minimized to obtain minimum tilt of the piston. The minimization of the piston tilt eventually leads to the reduction of engine noise.
