Seat 모듈 내구성 평가를 위한 가속 진동 내구 시험 방법 개발

Recently it is very highlighted to reduce the energy and fuel consumption of vehicle. Al and Mg material is preferred to reduce weight for fuel efficiency improvement to steel material for body, chassis, seat module, etc. In this paper we developed accelerated vibration fatigue test method and reproduction vibration test method on proving ground in order to durability evaluation of seat module. We tested the made by steel and Mg seat by vibration tester. Fatigue damage spectrum is made by real vehicle test data of general roads and of proving ground to consider operation profile of target PSD. It is proved to be useful to test seat module and is possible to reduce the time and costs.
