根据目前驱动轴设计中存在的在车辆极限工况下其实际需要长度无法准确测量的问题，提出一种驱动轴长度与整车匹配设计方法，即根据整车悬架硬点参数建立前悬架和驱动轴的运动模型，得出驱动轴移动节所有工况构成的摆角-位移V形曲线，由此判断驱动轴长度能否与整车相匹配。通过整车试验验证可知，试验结果与该方法的设计结果一致。

In the extreme operating conditions, the demanded length of the currently designed drive shaft can’t be measured correctly. To solve this problem, a matching design method of drive shaft length to vehicle is proposed in this paper, that is, construct kinematic model of the front suspension and drive shaft according to suspension hard-point parameters, to derive the V-shaped oscillating angle-displacement curve constructed with all the conditions of the drive shaft, therefore to determine whether the drive shaft length is matched with vehicle. It is concluded from vehicle test that this test method is consistent with result of this design method.
