仪表横梁刚度对方向盘振动影响的研究

摘要

Along with the development of the auto industry and the popularity of automobile in people's lives,people's comfortable demand on the car is becoming higher and higher.When people evaluate the comfort of the car,they use a combination of subjective evaluation and objective measurement.The vibration of steering wheel has become one of the most common complaints from the customers.A car is taken as the research object,and the combination of objective parameter measurement and vehicle comfort subjective evaluation is taken as the research method,analyzing the effect of the motormeter beam stiffness on the steering wheel.And then through the experiment data of the test, some solutions to the vibration of steering wheel are put forward.%随着汽车工业的发展及汽车在人们生活中的普及,人们对汽车舒适性的要求越来越高.汽车舒适性现在主要采用成员主观感觉为主,客观参数测量为辅的方式进行评价.目前影响驾驶员舒适度的因素有很多,其中方向盘振动是影响汽车舒适性的重要方面,直接影响到驾驶员的疲劳程度.以某汽车厂某款轿车为研究对象,针对其方向盘振动的问题,采用客观参数测量与主观评价相结合的方法分析了仪表横梁刚度对方向盘振动的影响,通过改进前后实验数据的比较,提出解决怠速方向盘振动问题的方案.
