针对某HPD柴油机热平衡的仿真研究

摘要

以某大功率密度柴油机为研究对象，基于GT-power软件建立其发动机模型，对其工作过程进行仿真计算，将仿真结果与试验结果进行比较，吻合良好，误差较小。在此基础上对该发动机在速度特性和负荷特性时的热平衡进行仿真计算。%This paper uses the professional engine analysis software GT-power to model a HPD (High Power Density) diesel engine. The working process simulation and computation of the HPD diesel engine are validated. From the contrast test results and computation results, there is good agreement and small error. On this base, the effect on the performance of the diesel engine caused by engine speed and load are analyzed.
