摘要 以某型地铁车辆转向架构架为研究对象,利用连续小波变换和奇异值分解的方法对运营状态下转向架构架的模态参数进行了识别。结果表明,识别的模态参数与有限元计算结果一致。 With the frames of a certain type of metro vehicle bogies as the object of research,the methods of continuous wavelet transform and singular value decomposition are used to identify the modal parameters of bogie frames in operation.The result shows that the modal parameters identified are identical with the result of finite element calculation.
