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。
This paper reviews and contrasts the existing driver response behavior models for vehicle driving in wind environment. By adopting the improved Baker driver response model, the vehicle movement balance equation, deformation and force Coordination condition, the state vector space equation of vehicle accident analysis model which introduced the driver reaction behavior model was established and the equation of motion of the two subsystems of automobile and bridge established by the wind-vehicle-bridge system which did not introduce the driver reaction behavior model , The equation of motion of wind-vehicle-bridge system under random traffic flow, which is introduced into the driver reaction behavior model, is established. The method of solving this equation is studied and the corresponding analysis module is compiled. The existing vehicle accident evaluation The criterion is improved, and the critical speed of wind-induced vehicle accidents corresponding to different wind speeds is given. The results show that the analysis module introduces driver reaction behavior model so that traffic safety analysis and comfort evaluation can be carried out at the same time.
