Low Frequency Vibration of the Sprung Mass on Front Outer Wheel in Cornering

선회 시 차량의 외측전륜 스프링 상질량의 저주파 진동

During the test drive of developing vehicle, a low frequency vibration of sprung mass on front outer wheel has been frequently observed in cornering with some speed. The purpose of this paper is to investigate the low frequency vibration of the sprung mass. The analysis result shows that the low frequency vibration is caused by sudden migration of the center of gravity of vihicle and it is determined by geometric points of suspension.
