摘要: 对高速公路合理限速值的确定方法进行了研究, 以多体动力学仿真软件ADAMS为平台, 建立了车辆模型、道路模型、车-路耦合模型、车辆行驶过程仿真试验模块和车辆安全状态识别模块, 并开发了高速公路车-路条件下安全速度仿真识别系统。运用该系统对车辆在弯道与下坡路段的行驶状况进行了虚拟仿真分析。试验结果表明: 车辆在弯道与下坡路段的安全行驶极限速度仿真结果与标准标定的运行速度的相对误差为1.05%~3.80%, 该仿真识别系统可行。Abstract: The determined method of rational value for limit speed on freeway was studied, correlative simulation models and modules were established based on multi-body dynamics simulation software ADAMS.The models and modules included vehicle model, road model, vehicle-road coupling model, simulation test module of vehicle operating progress and identification module of vehicle safety status.The simulation and identification system of safety operating speed on freeway were empoldered, and the simulation analysis of vehicle operating statuses on curves and at downhill sections was done by using the system.Test result shows that the errors between the simulation values and standardization values of safety limit speed are in the range of 1.05% to 3.80%, so the simulation and identification system is feasible.
