对现有解决风环境下车辆行驶问题的驾驶员反应行为模型进行了回顾和对比,采用改进的Baker驾驶员反应行为模型,引入了考虑驾驶员反应行为模型的车辆运动平衡方程、变形以及力的协调条件,建立了引入驾驶员反应行为模型的车辆事故分析状态矢量空间方程,将其与以往未引入驾驶员反应行为模型的风-汽车-桥系统所建立的汽车和桥梁2个子系统运动方程进行耦合,从而建立了引入驾驶员反应行为模型的随机车流下的风-汽车-桥系统运动方程,并对该方程的求解方法进行了研究,编制了相应的分析模块;对已有的车辆事故评价准则进行了改进,给出了对应于不同风速的风致车辆事故临界车速。结果表明:该分析模块由于引入了驾驶员反应行为模型,从而可以同时进行行车安全性分析和舒适性评价。
On the basis of review and comparison of the current driver response behavior models which deal with the vehicle running problem subjected to wind,using improved Baker driver response behavior model,the vehicle motion equilibrium equation and the harmonic condition of deformation and force that took into account the driver response behavior model were induced.The state vector spatial equation which could analyze vehicle accidents related to driver response behavior model was established.Authors coupled the supposed equation with the former two sub-system motion equations of vehicle and bridge from wind-vehicle-bridge system without taking account into driver response behavior model.The wind-vehicle-bridge system motion equation of stochastic vehicle stream considering driver response behavior was presented,and the solution method of state equation was studied.The analytical module of stochastic vehicle stream considering driver behavior was designed.The current wind-induced accident criterion was improved and some accident critical vehicle speeds under various wind speeds were calculated.Results show that due to the introduction of driver response behavior model for this analytical module,the vehicle running safety and comfort evaluation can be analyzed in the meantime.
