Research on the Device for High-Speed Front-Wheel-Drive Automobile Safe-Assistant Detecting on the Roller Bench

Research on the dynamic instability of the front-wheel-drive cars with high-speed movement on the roller bench.The paper illuminates the mechanism of the front-wheel-drive cars transverse-swing phenomenon in the high-speed detection items.The device for high-speed front-wheel-drive automobile safely and fast detecting on the roller bench has been designed based on the dynamic instability research.It can ensure that the high-speed detecting project could run safely and the detection data would be more exactly.From the field contrastive test,the correctness on the analysis of the front-wheel-drive cars running instability on the roller bench has been proved.The valid and reliable of the safe-assistant device design has also been testified.
