Simulation Study and Application on HPDC Process with Automobile Part

Abstract

In this research, Computer Aided Engineering (CAE) simulation was performed by using the simulation software (Z-Cast) in order to optimize casting design of an automobile part (steering wheel housing) which is well known and complicated to achieve a good casting layout. The simulation results were analyzed and compared with experimental results. During the filling process, internal porosities caused by air entrap were predicted and reduced remarkably by the modification of the gate system and the configuration of overflow. With the solidification analysis, internal porosities caused by the solidification shrinkage were predicted and reduced by the modification of the gate system.
