Performance extraction and simulation research on door back plate clip of certain vehicle
To solve the issue that the door back plate clip falling of certain vehicle,a simulation simplification method for clip connection is proposed.Based on the free falling test on clip pulling,the dynamic viscous damping coefficient is obtained.The static stiffness parameter,the dynamic damping coefficient and the failure parameter of clip are substituted into the simplified model,high-speed door closing of the vehicle door is simulated,the failure situation of clip under the strong closing condition of the door is verified.The results show that the simulation simplification method for clip connection can predict the failure risk of door back plate clip effectively.
