摘要
汽车振动是影响舒适性的主要因素之一,如何采用有效的技术手段测量分析汽车的振动,日益受到人们重视。采用LMS多分析系统,测试分析发动机振动随发动机转速变化的关系。结果发现,发动机二阶振动是引起车内噪声的主要原因。通过测试悬置系统隔振性能,为进一步提高系统隔振性能提供依据。
Vehicle vibration is one of the major factors that affect the comfort of passengers.How to measure effectively and analyze automotive vibration is becoming more and more important.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.To provide the basis for isolation for enhancing the performance of the system further,Isolation Mounting System by testing the performance.
