유연 다물체 동역학 해석을 통한 휠로더의 피로 해석 방법 개발 (Development of fatigue analysis method of the wheel loader through flexible multi-body dynamics simulation)
Abstract :
In order to increase the completeness of the wheel loader, it is desirable to measure the durability of each part of the design process to predict the weak portion in advance. In this paper, the wheel loader simulation for the Front Frame is performed for the specific operations (V-cycle) by using the Durability toolkit of RecurDyn. In this application program, the fatigue analysis is separated three steps. The first step is to search the weak portion of the wheel loader. Next step is Rainflow counting process. The last step is to perform the fatigue analysis using the load history which is already calculated. The result of fatigue analysis is also verified by the experimental data.
