The main cause of failure of the secondary vertical damper is oil leakage from damaged oil seal resulting from its repetitive vertical contact with the rod. It is necessary to study an optimum design of the cross-sectional shape of oil seals, to make a seal that can be mounted on various dampers and prevent common failure of existing dampers and extend the life-span of oil seals. In this study, to minimize the maximum principal strain at vulnerable points of the damper, the optimal cross section of the damper oil seal was found using the POINTER algorithm. Moreover, nonlinear material properties of the rubber are determined by Mooney-Rivlins’ hyperelastic model. Nonlinear finite element analysis confirmed that the maximum principal strain at the oil leakage point had a 20% decrease from the initial design to optimum design. Fatigue life was also predicted using the same method used to find the fatigue properties. Moreover, a fatigue rig test of the component was performed to examine the structural integrity.
