摘要：
Dynamics test, mainly modal test, was finished aiming to analyze and estimate the mechanical performance of the parallel robot. The LMS testing system was applied to accomplish the modal analysis. The dynamics performance of the robot was evaluated and the modal parameter variations were also achieved based on the modal analysis of the simplified model. The modal analysis of the entirety model was explicated with modal shapes of the typical configurations as examples. The key modes which affect work precision were found out and the parameters to be improved were confirmed. The result of this test is useful to improve the dynamics performance of the robot. It is validated by comparative analysis that the testing process put forward in this work is applicable to other modal tests on mode variation.
