模态分析技术在摩托车振动改进中的应用

Application of Mode Analysis in Motorcycle Vibration Improvement

介绍了模态分析的基本原理,对摩托车开发中的一个振动案例进行了阐述。在此案例中,采用了模态实验、振动信号频域诊断与CAE模态分析技术相结合的技术路线,解决了该车的振动问题,为今后解决此类问题提供了有效的解决思路。

This paper introduced the principle of mode analysis. Taking a motorcycle vibration problem as example, we applied the mode test, the vibration signal frequency domain diagnosis and CAE mode analysis to solving the problem, offering an effective method to deal with this kind of problems.
