2채널을 이용한 차량 Rear Axle 내구시험 연구

In general, there is not much correlation between the 8ch test and the DV test for rear axle. So OEM and supplier have spent too much development cost and time. Actually, the rear axle met the target for DV Test with initial specification, but didn’t met for 8ch Test. so it was inevitable design change. Though the rear axle was changed the design, it didn’t meet the target for 8CH Test. Therefore, in this paper, the method to improve correlation is suggested using 2CH Test.
