| 摘 要： | 为提高多轴汽车操纵稳定性，针对五轴全轮转向汽车的高速同相位转向工况，进行了受力分析，建立了运动微分方程，利用Fiala轮胎模型建立了轮胎的力学模型，利用LabVIEW软件建立了整车的动力学仿真程序。通过虚拟试验仿真分析，发现采用全轮转向，可以使后轴车轮较早地参与转向，从而提高了汽车的转向响应速度，并使车身侧倾角由7．5°减小为4°。 |

| Abstract: | In order to enhance the handling stability of multi-axle vehicle,a mechanical analysis on high-speed inphase steering conditions of five-axle vehicle with all-wheel steering has been done,and the related kinematics differential equations of vehicle with 24 freedom degrees were established,the mechanical model of the tyre has been built based on Fiala-tyre model.Finally,VI sub-function compiled by C language was inserted into LabVIEW graphical codes by MathScript node.The whole vehicle dynamics simulation pr... |
