Numerical Investigation and Fatigue Life Estimation of Conventional and Modified Piston of Diesel Engine

摘要

Nowadays engine components are subjected to higher load at elevated temperature than before, due to the increase requirement regarding weight, performance and exhaust gas emission. Thus, Fatigue due to simultaneous thermal and cyclic loading become determinant among the damage forms. At the same time, there is the need to reduce development time and cost to handle the growing number of model variant. Therefore, the development of suitable simulation tools, which reduces the number of necessary component tests, seems to be very rewarding. By using special material (aluminum alloy) we can reduce the fatigue load (Thermal and cyclic) on the piston by using finite element analysis, ANSYS work bench 14.5 version.
