Design and optimization of engine plastic cylinder head cover

Abstract

Based on characteristics of plastic head cover, the paper carried out 5 design concepts to improve its NVH property. It’s useful to improve NVH properties of product if follow the concept when design or optimize a head cover. In this paper, finite element and multi-body dynamics analysis methods were used to analyse a plastic head cover firstly. At second the head cover was optimized with the concept in the process. Finally, the plastic head cover met the development target. Test results proved the reliability of design concepts as well.
