Abstract

In this study, a hydraulic system of a mini-loader is modeled, and the model is validated by comparing the simulation results to the experimental results. A load force acting on the structure of the mini-loader is obtained from the simulation of the hydraulic system, and the structural analysis via finite element method is performed using the obtained load force to evaluate the structural safety of the loader. For the mainframe that requires additional strengthening according to the structural analysis, the optimum design parameters are proposed using the design of experiments to improve strength without additional mass.

본 연구에서는 미니로더의 유압시스템을 모델링 하였고, 시뮬레이션 결과와 실제 실험 결과의 비교를 통해 시뮬레이션의 타당성을 검증하였다. 그리고 미니로더의 유압시스템 해석을 통해 구성부품에 가해지는 하중을 구하였으며, 그 하중데이터를 바탕으로 구조해석을 진행하여 구조안전성을 평가하였다. 구조해석결과 강도 향상이 필요하다고 판단되는 main frame에 대해서는 실험계획법을 이용하여 중량은 유지하면서도 강도는 향상시킬 수 있는 최적 설계치수를 제안하였다.
