摘　　要：以某型号自卸车冷却系统为研究对象,利用散热器风室试验台对其中冷器及水散热器的散热性能进行测试。运用热管理一维仿真软件建立该自卸车冷却系统模型,分别在发动机最大转矩及最大功率工况下,对自卸车冷却系统的热平衡状态进行仿真计算,并将计算结果与整车道路试验数据相比较,验证计算结果的准确性。试验证明该仿真方法行之有效,可用于自卸车冷却系统的匹配设计。Simulation and test on cooling system of dump trucks.We placed a certain dumper's cooling system as an object for our study,by utilizing radiation function of the cooler and radiator.And then,we used 1-D heat management software to have constructed a model for the truck's cooling system while computing the simulation under the engine's max torque and max power rate conditions,and under heat-balance conditions of the dump truck,respectively,before comparing the computation results with those of whole-car road test to see calculating precision.Test results show that the simulation is feasible and effective that can be used for match-up design of cooling system for dump trucks.
