摘　　要：基于斜盘发动机结构参数,依次建立了其缸内工质状态模型、流率模型和散热损失模型,并对缸内工质质量、内能、压强和温度等热力学参数的变化趋势进行了仿真分析,得到了发动机稳态循环的示功图。仿真结果表明:所建立模型符合斜盘发动机六个热力过程。然后,对示功图进行分析,指出了提高发动机功率的途径。Based on the structural parameters of the swash-plate engine, the models for the working state, flow-rate and heat dissipation were established respectively. Then the simulation and analysis of the variation trends of thermal parameters such as working medium mass, energy, pressure and tem- perature in the cylinder resulted in obtaining the P-V diagram of the steady-state cycle. The results in- dicate that the models are suitable for simulating the six thermal processes of the swash-plate engine. According to the analysis of the P-V diagram, the engine power can be improved.
