摘　　要：本文基于硬件在环的仿真结果评估某重型柴油机的高原性能,作为KULI计算的输入对其进行高原热管理仿真计算,针对高原环境,分析该柴油机匹配的冷却系统在高原环境下的极限使用环境温度。根据硬件在环的仿真计算结果,该柴油在高原4 000 m海拔下,总热量、有用功、中冷器和散热器带走的热量、进气流量都有变化。通过一维仿真与硬件在环相结合的仿真计算方法,对柴油机进行高原热管理分析,准确可靠,误差可控。该方法正向地提升高原柴油机冷却系统匹配效率,提高柴油机在高原上的热可靠性。This paper assesses the plateau performance of a heavy diesel engine based on hardware-in-loop simulation results,performs the plateau thermal management simulation calculation as input to the KULI calculation,and analyzes the extreme ambient temperature of the diesel engine-matched cooling system in the plateau environment for the highland environment.Based on the hardware-in-the-loop simulation calculation,the diesel fuel had a total heat,useful work,heat taken away by the intercooler and radiator,air flow at an altitude of 4000 meters above the plateau,which varies all.Through the simulation calculation method,which combines 1D simulation with hardware in the loop,the diesel engine is analyzed for plateau thermal management,accurate,reliable,and error-controlled.This approach is improving the efficiency of the altitude diesel cooling system match and improving the thermal reliability of the diesel engine on the plateau.
