Abstract：The passive variable damping device can provide variable damping force and does not need energy supply. Its variable damping characteristics have been verified by experiments. The maximum damping force and the damping force time-history of the device are closely related to several design parameters. The research on these two factors is of great significance to the engineering application of the device. Based on the design and test of the passive variable damping device in the early stage, the finite element modeling and test verification of the device were completed by using the method of computational fluid dynamics, and the main design parameters of the device were analyzed, optimized design and performance test were carried out. The finite element analysis and experimental results show that the hysteresis curve obtained by the simplified model is in good agreement with the experimental results, which verifies the accuracy of the established model and simulation method; The change rate of the damping coefficient of the cross pass of different damping valves is different, which is suitable for different application scenarios; The optimal combination of the maximum damping force under the same condition is obtained through the combined analysis of the main parameters of the device, and the effectiveness of the optimal combination is verified by experiments. The research provides a good theoretical basis and experimental basis for the further development and application of passive variable damping device.
