가속 내구시험을 통한 유니버셜조인트 내구수명에 관한 연구

다국어 초록 (Multilingual Abstract)

Universal joint damage occurred during the operation of a combat vehicle. Damage to the internal bushing and cracks of the rubber cover occurred, and a design change was promoted based on the cause analysis and improvement measures. The failure of the bushing is due to the occurrence of expansion due to fatigue load when the rotation proceeds in the presence of the assembly clearance of the cross joint. In addition, cracks in the rubber cover are caused by the deterioration of the intermetallic rubber surface. Through this failure mechanism analysis, severe durability factors were selected and accelerated durability tests were conducted. In this paper, the final limit life of universal joints can be evaluated through accelerated endurance tests. Furthermore, the endurance life of the product before the change and the endurance life of the product after the change are compared to prove the improvement effect through design changes.
