The Evaluation of Vehicle Vibration Comfort Based on Annoyance Rate

Tang Chuanyin Zhang Tianxia Ji Wei(1.Insitute of vehicle engineering, School of Mechanical Engineering and Automation, Northeastern University ,Shenyang,110004;China 2.Fushun Anyi Life-saving Equipment CO.,LTD , Fushun 113006, China)  
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.
