Research on Damping Contribution Rate of Key Parameters of Valve-Controlled Damping Adjustable Damper

Valve-controlled damping adjustable damper has the characteristics of simple structure and damping, it always been a hot research topic. This paper establishes mathematical model valve-controlled designs experiment compression stroke recovery stroke. Through simulation experiment, accuracy is verified, contribution rate different key parameters under excitation speeds analyzed. The results show that can well describe working state damper. obtained. constant through-hole diameter decreases gradually after valve opened for first time. With increase speed, plate equivalent thickness maximum limit clearance check play major role in rate. screen out parameters, improve development efficiency damper, provide guidance design optimization.
