Abstract
As a consequence of the trend towards lightweight construction, plastic components are increasingly being used in automobile manufacturing. This includes engine components which emit a considerable degree of noise, such as valve covers and oil pans. Within the context of a ZuTech research project carried out at the Institute for Internal Combustion Engines (VKA) at RWTH Aachen University and the Institute of Plastics Processing (IKV) at RWTH Aachen University, a method of predicting the acoustic behavior of plastic components has been developed and validated. The assignment was given by the Forschungsvereinigung Verbrennungskraftmaschinen e. V. (FVV, Frankfurt / Main, Germany) under No. 899 and the Vereinigung zur Forderung des IKV. Integrating the method into the development process enables local weaknesses of the structure to be detected and the acoustics to be optimized at a very early stage.
