| 摘 要： | 建立了某国产重型商用车驾驶室白车身的有限元模型并进行计算模态分析.同时采用多输入多输出方法对实际白车身结构进行模态实验并经处理得到实验模态.应用模念相关分析理论计算了计算模态与实验模态之间的振型相关度.结果表明:二者具有很高的相关性,有限元模态分析能够足够精确地确定实际结构的整体动力学特性.

| Abstract: | The finite element model for the cab body-in-white(BIW) of a home-made heavy commercial vehicle is set up,and based on which a modal analysis is performed.Meanwhile a modal test on real BIW structure is also conducted using multi-input multi-output method with experimental modes obtained through processing.Then the degree of correlation between calculated modes and experimental modes is calculated by applying the theory of modal correlation analysis.The results show that the calculated modes well accord wit... |
