摘要
为获得三支点叉车转向时,转向齿轮的动力学变化规律,提出基于Hertz理论和虚拟样机仿真的方法.考虑叉车转向的实际情况对助力转向与回正过程中齿轮的转角、角速度、角加速度、圆周力、径向力、轴向力、法向载荷的变化规律进行了仿真研究.结果表明:运用Hertz理论和虚拟样机方法可以有效实现对EPS系统转向齿轮啮合的动力学研究,从而为电动助力转向系统的设计与改进提供理论支持及参考.
In order to obtain the dynamic changing pattern of three fulcrum forklift steering gear,a method based on the simulation of virtual prototype and Hertz theory was proposed.During the process of the power steering and the power steering reversal,considering the actual situation of forklift steering,the research on the dynamic changing pattern of the gear angle,angular velocity,angular acceleration,angular acceleration,circumferential force,radial force,axial force,normal load was carried out.The results show that the dynamic research on steering gear meshing of the EPS system can be effectively realized by the Hertz theory and virtual prototyping method,which can provide theoretical support and reference for the design and improvement of electric power steering system.
