基于CATIA参数化建模校核Ackermann误差的方法

Ackermann error checking method based on CATIA Parametric-modeling

介绍了Ackermann误差概念和传统校核方法的局限性,提出采用CATIA参数化建模方式,建立全空间转向机构硬点-骨架模型,依靠CATIA参数化驱动功能,通过改变参数得到非常精确的Ackermann误差,并且利用参数与设计表关联,快速得到所有车型转向系统的骨架模型,实现了高效、准确校核大量车型Ackermann误差的目的。

This article presents the concept of Ackermann error and the defects of traditional checking method, building full-geometrical steering hard-point model by the parametric- modeling method to obtain the precise Ackermann error with the function of parameter-driven, realized the goal of checking Ackermann error of a mount of vehicles with high efficiency and precision utilizing the Design table to build the skeleton model of steering system of all vehicles.
