The planetary transmission mechanism is the core component for realizing the maneuverability of high-speed tracked vehicles. The modal test can determine the transmission characteristics of the planetary transmission system structure, and can check whether the dynamic characteristics of the planetary transmission system meet the design requirements. It is the basis of studying the dynamic characteristics of planetary transmission mechanism. In this paper, the free mode of the planetary variable speed mechanism is tested by using the free modal test method, and the modal analysis is carried out by using the finite element method. The results show that the vibration modes of the planetary variable speed mechanism are consistent with the results of finite element simulation, and the deviation between the measured modal frequency and the simulated modal frequency is less than 2%. The modal test provides the basis for the verification of the structural dynamic model and the dynamic coupling analysis of the planetary transmission system.
