摘　　要：车辆在弯道发生事故较多,不同弯道安全车速的获取对车辆行驶安全具有重要的意义,但人工测量不同弯道车速时的危险性较大。以某6906型的中型客车为研究对象,采用Trucksim仿真软件建立该车的整车动力学模型,根据GB/T 6326-2014中蛇形实验的试验数据与仿真数据对比验证模型的有效性。在此基础上,研究仿真不同弯道半径(10~300 m)下的安全通过车速,对比简化模型计算车辆的理论安全车速。研究结果表明:随着弯道半径的增加,客车的安全车速逐渐增大,但并不是呈线性增加。At road bends,there is a high probability of a vehicle accident.The acquisition of safe speeds in different corners has important significance for driving safely.But it is more dangerous to measure the speed of different bends manually.In this paper,a medium-sized passenger car of LCK6906H5A is studied,the vehicle dynamics model was built using the Trucksim simulation software.According to the test data of the serpentine experiment in GB/T 6326-2014,which is compared with the simulation data,the validity of the model is verified.Furthermore,under different road turning radius(10~300m)conditions,the safe driving speed of the vehicle was studied and simulated,compared with the simplified model,wehave calculated the theoretical safety speed of the vehicle.The results show that as the radius of the curve increases,the safe speed of the passenger car gradually increases,but does not increase linearly.
