摘　　要：针对重载货车在长大下坡路段行驶事故频发的问题,基于升温和降温两个过程,采用理论建模和试验研究相结合的方法,建立了持续制动装置和行车制动器联合作用时的重载货车坡道行驶制动鼓温升模型,对重载货车长大下坡行驶温升特性进行研究,计算车辆行驶时的制动鼓温度,预测制动鼓效能失效位置,从而确定设置控速设施的位置。According to the high incidence of heavy-duty truck accident in long and steep sections, based on heating and cooling,combining theoretical modeling and experimental research,the paper established brake drum temperature rise model for heavy-duty truck driving on ramp when continuous braking device and driving brake acted together.To determine the location of setting speed control facilities,the paper also studied temperature rise characteristic of heavy-duty truck driving in highway long and steep sections,and calculated the brake drum temperature when the vehicle was running,thus predicted braking effectiveness failure position.
