摘　　要：转向系统作为驾驶员直接操纵的安全系统,不仅需要考虑驾驶安全,还应将客户感知作为重要考虑因素,为驾驶员提供稳定,平顺的驾驶感受。文章从理论分析入手,阐述了滚珠滑动式中间stick slip的产生原理,建立受力模型,并针对其结构和受力情况提出了两条优化方案,抑制stick slip问题的产生。As a safety system directly operated by drivers, steering system should not only consider driving safety, but also take customer perception as an important consideration to provide drivers with a stable and smooth driving experience. Starting with the theoretical analysis, this paper expounds the generating principle of the ball sliding intermediate stick slip, establishes its force model, and puts forward two optimization schemes according to its structure and stress condition to restrain the occurrence of the stick slip problem.
