摘要
方程式赛车方向变化不灵活是一个有待解决的问题,根据双臂悬架主销内倾的计算公式,确定了正时侧向偏转角速度与主销定位角的数学关系,采用多体动力学仿真软件对主销定位角进行了仿真,并采用ANSYS建立了赛车的虚拟样机模型。根据优化后的赛车多体动力学仿真结果,优化后的参数对整车的操作和稳定性具有明显的改善作用,在赛车返回正函数的假设下,赛车方向变化的灵活性有所增加。
It is a problem to be solved that the direction of racing car is inflexible. According to the calculation formula of kingpin inclination of double arm suspension, the mathematical relationship between the speed of timing lateral deflection angle and kingpin positioning angle is determined. The multi-body dynamics simulation software is used to simulate the kingpin positioning angle, and the virtual prototype model of racing car is established by ANSYS. According to the multi-body dynamics simulation results of the optimized car, the optimized parameters have a significant improvement on the operation and stability of the car. Under the assumption that the car returns to a positive function, the flexibility of the car direction changes has increased.
