Abstract: The nonlinear characteristics of the structure of the damper make its own frequency influenced by the environmental factors, which is the difficulty in the frequency design of the damper. This paper mainly studies the influencing factors of the frequency characteristics of damper, and concludes that the frequency characteristics decrease with the increase of temperature and excitation. Combined with a case, based on the boundary conditions of temperature, acceleration and frequency at the maximum resonance of the whole vehicle, a 6.6 kg damper is calibrated on the bench, and it is verified on the whole vehicle.
