ABSTRACT

With the development of shock absorber calibration technology, there is still a lack of a positive development dimension in the setting of shock absorber damping force. Based on the bench test data of shock absorbers of different types of competing models and the design principle of the relative damping ratio of shock absorbers, this paper sets the bandwidth of the relative damping ratio for recovery and compression of shock absorbers of different models at different speed points, and then sets the bandwidth of the damping force of shock absorbers. Based on the research on the theoretical optimal damping force curve of shock absorbers, it was found that the optimal damping force curve is within the set range of the damping force bandwidth, effectively verifying the rationality of the relative damping ratio bandwidth setting and providing a basis for the forward development of shock absorbers.
