摘要
利用ADAMS/V iew建立了多轴汽车的多体动力学模型,并进行了停车场出车和高速行驶避障的双相位转向虚拟试验,通过试验分析发现,低速行驶时,采用逆相位转向可以大大缩小转弯半径,提高汽车的机动灵活性;高速行驶时,采用同相位转向可以缩小汽车横摆角速度,提高操纵稳定性,减少汽车发生甩尾的可能性。
The muhi-body dynamics model of multi-axle vehicle has been built with ADAMS/View, and the virtual experimentation of starting from park and avoiding barrier in high-speed has also been processed. After experimentation has been analysed, it was found that in low-speed the steering radius was shorten with adverse-phase steering,and maneuverability was improved, and in high-speed the yaw rate was reduced with in-phase steering, and controlling stability was improved, and possibility of swing of afterbody was minished.
