Abstract

In this study, the life evaluation due to the structural configuration of bumper attached at the front side of ATV vehicle is studied on the basis of fatigue analysis. As the purpose of this study, the characteristic of bumper exposed on the repetitive loading condition like the vibration is understood. The position of crack happened at the fatigue situation is grasped in advance and complemented in advance. It is considered that the multipurpose vehicle is designed to not be driven on the paved general road but the rough road like the unpaved load. And the weak part of bumper is understood through the study of life evaluation on this driving environment. The durability can be improved by doing the safe design of automotive bumper on the basis of the analysis result. And it is possible to be grafted onto the convergence technique at design and show the esthetic sense.

본 논문은 ATV차량의 전면에 부착되는 범퍼의 구조적인 형상에 따른 수명평가를 피로해석을 토대로 연구하였다. 본 연구의 목적은 진동과 같이 반복적인 하중조건에 노출되는 범퍼의 특성의 파악하며, 여러 가지 피로 상황에서 발생되는 크랙의 위치를 사전에 파악하며 이를 보완하기 위함이다. 다목적 차량이 일반적인 포장도로가 아닌 비포장도로와 같은 험로를 주행하게끔 설계됨을 고려한다. 그리고 이러한 주행환경에 대한 수명평가 연구를 통해, 그 범퍼의 취약부위를 파악한다. 본 연구의 해석결과를 토대로 자동차 범퍼의 안전설계를 함으로서 내구성을 향상하고 설계에 있어 융합기술에 접목하여 그 미적인 감각을 나타낼 수 있다.
