摘要
Noise and vibration of vehicle is a complex problem, and affect automobile ride comfort and structure strength. How to measure effectively and analyze automotive vibrations has becoming key research fields to the engineers. In this paper, the LMS multi-analysis system is used to determine and analyze the vibration varying with engine speed near the engine. Test results show that the main reason of engine noise is second-order vibration. By studying the isolation Mounting of the testing suspension system, can reduce Noise and Vibration of Automotive.
