摘要： 阐述了振动舒适度的传统评价方法.采用人体对振动主观反应的模糊随机评价模型,建立了相应的模糊隶属度与概率分布形式,提出了基于烦恼率模型的振动舒适度评价方法.应用Matlab/Simulink软件建立了4自由度半车振动的仿真模型,得到了车身加速度在受到路面随机激励时的烦恼率模型.并且与传统的1/3倍频程分析对比法中的疲劳-效率降低界限进行比较,验证所提出的方法的正确性.基于烦恼率模型的振动舒适度评价方法,可以进一步对振动引起的不满人数进行定量评估.

Abstract: Discussing the traditional evaluation of comfort ability during vehicle vibration, a fuzzily random evaluation model is proposed on the basis of annoyance rate for human body's subjective response to vibration, with relevant fuzzy membership function and probability distribution given. The software Matlab/Simulink is applied to developing a nonlinear vehicle vibration model with four degrees of freedom for simulation, of which the vehicle is subject to randomly irregular excitations exerted by road surface. Then, a model of annoyance rate is obtained in terms of vehicle body acceleration. Compared with the fatigue-efficiency reduction criterion in the conventional contrast with 1/3 multiple frequency internal, the validity of the newly proposed evaluation method is verified. The evaluation method based on annoyance rate can further estimate quantitatively the number of passengers who feel discomfort due to vibration.
