Abstract
In order to solve the problem that modals of the trimmed car body are difficult to identify, both frequency-domain and time-domain identifications are used for the modal test of the trimmed body of a car on the basis of the structure’ s linearity inspection. The test scheme and signal acquisition technique are introduced and the identification methods are comparatively studied. Of these methods, the successful application of the stochastic subspace identification provides a new way for the body modal test. Finally, the comparison of results from the test and FEA verifies the accuracy of the trimmed body modeling analysis. The determined modals of the trimmed body lay a foundation for the analysis of NVH performance.关键词
