Abstract
The small-sized liquid damping time delay mechanism has the problems of large computational volume in the dynamic CFD simulation. Based on the establishment of the dynamic model of the damper, this paper analyzes the relationship between the liquid damping force and the influence factors such as the orifice hole length, temperature, and piston movement speed through the combination of CFX static simulation and CFD dynamic simulation. The parametric representation of damping force and influencing factors is obtained by data fitting and correction. The fitting model is tested under multiple working conditions, which shows the effectiveness of the method.
