| 摘 要： | 为解决某中型客车怠速方向盘振动过大问题,采用试验模态分析法,运用BK测试系统分析发现方向盘振动过大的主要原因.通过更换刚度更大方向盘提高固有频率的措施,避免发动机的怠速频率与转向管柱共处半功率频带,从而改善怠速方向盘振动过大的问题.试验验证表明:方向盘怠速振动峰值降低51.4%,达到预期效果,提高车辆的驾驶舒适性并为解决同类问题提供一个可行方法.

| Abstract: | This paper aimed at reducing violent vibration of steering wheel of a medium-size passenger coach in idle condition by using experimental modal analysis. It is found that the closeness of the third modal frequency of steering column to the engine idle frequency in the vibration within the half power bandwidth was the main factor causing the wheel vibration. Steering wheel with higher stiffness raised the frequency and kept the engine idle speed frequency from within the half power bandwidth so that wheel vibration at idle speed was reduced. The results show that peak wheel vibration was thus reduced by 51.4%, meeting the expected effects with improved driving comfort and making a solution to similar oroblems. |
