| 摘 要： | 在目前的动力学研究中,无法对不同参数下的相似刚体模态进行计算机自动识别.基于模糊数学中的最大隶属度原则,对刚体振动模态进行相似性研究,得到了准确度较高的相似模态识别方法,能够对随着参数变化而变化的刚体模态进行自动识别和归类;绘制出了准确的参数-模态曲线,为机车的悬挂系统优化中刚体模态分析的后处理提供了有效的手段.

| Abstract: | In current studies of vehicle dynamics,no method for computer program is available to identify automatically the similar rigid-body modals with different parameters.In this paper,the similarity of rigid-body modal is studied based on the principle of maximum subordination degree in fuzzy mathematics and a similar modal identification method with high-precision is found,which is not only able to identify but also classify the rigid body modals after the parameters have been changed.This method offers an effe... |
