Abstract

Noise Vibration Harshness (NVH) is one of the important factors affecting drivers when driving automobiles. This study tested various driving situations after attaching a triaxial accelerometer to major system devices of electric vehicles in Korea and Overseas. Wide Open Throttle (WOT) acceleration test, Virtual Engine Sound System) (VESS) noise test, constant speed driving test, and wind noise test were conducted. Noise level was measured using the SIEMENS program. The most prominent noise factor was verified. In this study, important factors affecting NVH were analyzed for electric vehicle development.

NVH(Noise Vibration Harshness)는 주행 시 운전자가 느끼는 자동차 중요 인자 중 하나이다. 본 연구는 국내와 해외 전기자동차의 주요 시스템 장치에 Triaxial Accelerometer를 부착 후 여러 주행 상황을 가정하여 시험한 결과이다. WOT(Wide Open Throttle) 가속과 VESS(Virtual Engine Sound System) 소음, 정속주행, 풍절음의 시험을 수행하였다. SIEMENS 프로그램을 사용하여 소음 레벨을 측정하고 가장 두드러지는 소음 인자를 검증하였다. 전기 자동차 개발을 위한 중요 인자를 분석하였다.
