In this study, a tuning jounce bumper with increased energy absorption was developed. The tuning jounce bumper is constructed by adding a support bumper to the jounce bumper. The support bumper helps in absorbing the impact energy in the initial, mid-term, and over-compression sections. Compression structure analysis was used in order to predict the LD performance of the support bumper. The conventional single jounce bumper and the developed tuning jounce bumper were applied to the vehicle dynamics model for the verification of ride comfort performance. Based on the international standard test ISO, it can be determined that the ride comfort has improved at various speeds(20, 30, 40, 50, 60, 70, and 80 km/h). Therefore, the tuning jounce bumper not only increased the energy absorption, as compared to the single jounce bumper, but it also enhanced ride comfort for impact at various speeds. |
