Local Strain Method를 이용한 Torsion Beam Rear Axle 내구시험의 Lab to Road correlation 방법 연구

다국어 초록 (Multilingual Abstract)

Chassis parts of vehicle has been tried to be validated through a bench test in lab. Instead of a full vehicle test on road that a lot of time and costs are required of. In case of a bench test in lab., it is very important to correlate with full vehicle test result on road. Actually, reliability of a test depends on the correlation. Therefore, many engineers are making an efforts to have good correlation. Generally a simulation test is regarded as the most reliable test method. In this sense, durability of chassis system could be evaluated with 8ch Multi Axial Simulation Rig. 8ch test is the highest level test in lab. to evaluate torsion beam rear axle durability and it is capable to simulate 8-DOF. The study of purpose is to improve correlation of results between road and 8ch lab test for torsion beam rear axle using local strain on the part. It is also to improve correlation on lab test.
