중형트럭 고기능 섀클 및 스토퍼의 구조에 관한 연구

The Truck suspension is one of the most important part to decide the durability performance of the commercial vehicle. Since the shackle & helper stopper, a core component for rigid axle supension, directly supports leaf spring, it needs strength and durability. In this paper, the test objective developed the 5 ton truck, Z directional durability test was carried out shackle & helper stopper. The durability test has been conducted under a driving condition of Z force mode by usieng hydraulic actuator for shackle & helper stopper. We"ve also carried out srtuctural analysis by utilizing ANSYS in order to predict for shackle & helper stopper durability.
