摘要： 针对传统的ISO动态舒适性评价标准只能定性地衡量振动舒适度，以及高速列车舒适度研究座椅人体分离等问题，把建筑学振动的烦恼率方法引入高速列车平顺性分析中并建立了“人-座椅-地板输入”的7自由度耦合仿真模型.在350km/h高速列车运行环境下，对模型应用烦恼率模型进行仿真，并和ISO评价法进行对比.结果表明基于烦恼率模型的高速列车平顺性分析能够比较好地弥补传统方法的缺陷，实现了评价结果的定量化.

Abstract: The traditional ISO dynamic comfort evaluation could only measure the vibration comforts qualitatively and the comfort of the highspeed train when seat and body separated. A nonlinear human bodyseat coupled simulation model with seven degrees of freedom is established considering the annoyance rate， which subjects to irregular excitation of a railway with speed of 350km/h. The model is simulated by annoyce rate， and its result is compared with that of the ISO evaluation method. The result shows that the ride comfort evaluation based on the annoyance rate model can compensate the defects of the traditional method， and the result of the evaluation can be quantitative.

Key words: highspeed train, dynamic comfort, annoyance rate, coupled simulation model, ride comfort
