Numerical Study on Dynamic Noise and Radiated Noise of Oil Sump

Abstract

This paper studies EQ4H engine oil pan. Finite element method and boundary element method are utilized to calculate and predict the vibration and noise radiation of the oil pan. Based on the analysis results, the oil pan is optimized and redesigned. By comparing the vibration and noise performance of the oil pan before and after optimization, the effectiveness of the optimized design is verified.
