摘　　要：阐述了车辆振动的传统评价标准,提出了基于烦恼率模型的平顺性评价方法。建立了四自由度车身振动模型,得到了车身加速度在路面随机激励下的烦恼率模型,提出了一种新的车辆平顺性分析方法。After discussing the traditional evaluation methods of vehicle vibration, the evaluation method based on annoyance models are derived. A nonlinear system with four degrees of freedom is established, which subject to irregular excitation from a road surface. The annoyance model of vertical acceleration of the vertical body is obtained. A new analysis method for evaluating vehicle vibration comfort is proposed.

关 键 词：烦恼率 振动舒适度 评价方法 振动模型
