摘　　要：乘用车开空调后方向盘抖动是车辆开发中常见的低频抖动问题。论文主要研究乘用车开启空调后,冷却风扇、压缩机、鼓风机与发动机同时运转激励,从而使方向盘抖动加大,给驾驶人员带来不舒服的感受,甚至进一步引发驾驶员抱怨索赔的问题,重点分析问题产生的原因,并制定对应的解决方案。研究结果表明,重新定义左右风扇转速、优化仪表横梁及右悬置结构、重新定义空调开启时发动机的转速能有效解决此类问题。Steering wheel shaking after turning on the air conditioner in passenger cars is a common low-frequency shaking problem in vehicle development.This paper focuses on the problem that when a passenger car is turned on with air conditioning,the cooling fan,compressor,and blower run simultaneously with the engine to stimulate,thus increasing steering wheel shake and bringing uncomfortable feelings to the driver,and even further triggering driver complaints and claims,focusing on analyzing the causes of the problem and developing corresponding solutions.The research results show that redefining the left and right fan speeds,optimizing the instrument crossmember and right suspension structure,and redefining the engine speed when the air conditioner is on can effectively solve such problems.
