Abstract: In order to analyze the influence of structural parameters of rubber pad on its damping capacity, the mathematical model of structural parameters on the stiffness of rubber pad is established based on response surface methodology, and the influence of structural factors on stiffness is analyzed. The failure mechanism of rubber pad under actual using conditions is discussed, and a new structure considering robustness is proposed. Compared with conventional structures, this structure can effectively reduce the probability of damping failure during the use of rubber pads without affecting the original damping capacity, and improve the reliability of rubber pads.
