콰이어트 가진기를 이용한 전자식 주차 브레이크 작동소음 시뮬레이션 기법 연구

Recently, as an application of EPB(Electronic Parking Brake) system, especially a motor-on-caliper(MoC) type, in the vehicles has been broadened, drivers’ complaint about operating noise of EPB has been larger. This paper focuses on not only the NVH characteristics between the 1 st and 2 nd generation of MoC, but also the simulation method using a quiet shaker without a MoC assembly. New simulation method shows good test results between vehicle test with a MoC sample and vehicle simulation test without a MoC sample using a quiet shaker. And this method will be a good simulation tool for noise design in the step of developing MoC.
