摘　　要：为了对车辆进行耐久性及一般排放试验,在实验室通常使用底盘测功机通过转鼓对车辆进行模拟道路试验,以期达到与实际道路试验同样的效果,但是在实验室内进行道路模拟实验,其模拟精度受到道路行驶阻力的测量及测功机摩擦阻力的测量精度等因素的影响。为了保证车辆状态的一致性和试验数据的稳定性,本文根据滑行阻力和速度的关系进行道路模拟实验标定车辆固定装置和试验前热车状况、驱动轮胎压力、驱动轮有效载荷等工况参数。To vehicles for durability and general emission test,usually in the laboratory using a chassis dynamometer by drum used for simulating the vehicle road test,in order to achieve the same effect with the actual road test,but in the laboratory road simulation test,the simulation accuracy of road resistance measurement and friction resistance are given to the factors of the measurement precision.In order to ensure the consistency of vehicle state and the stability of test data,this paper carries out road simulation experiments to calibrate vehicle fixed device,hot vehicle condition before test,driving tire pressure,driving wheel payload and other operating parameters according to the relationship between sliding resistance and speed.
