摘　　要：文章针对某轻卡在怠速开空调工况下方向盘抖动问题展开研究,通过方向盘振动测试与转向系统模态测试,分析并确定了方向盘抖动原因。利用有限元方法计算分析了主要零件参数对转向系统第一阶模态频率的影响灵敏度,最终提出了优化设计方案。根据设计方案进行了样件试制与装车,并进行了试验验证,结果表明方向盘抖动问题显著改善。This paper studies steering wheel＇s shaking problem of a light truck at the idle AC on condition. Vibration tests and modal analysis of the steering system have done for determine the cause of steering wheel＇s shaking. The modal sensitivities of the main part parameters on the first-order modal frequency of the steering system is calculated and analyzed using the finite element method. Finally, the optimal design scheme is put forward. The effectiveness and rationality of the improvements were verified through sample preparation, assembly and tests.
