对置式凸轮发动机热力学仿真

为了分析评估对置式凸轮发动机的性能状态,在该发动机关键部件运动学与动力学分析基础上,建立发动机热力学模型,利用改进的龙格一库塔算法进行热力学模型求解与性能仿真.研究结果验证该特种空间发动机在工作原理和结构设计上的可行性,提出若要进一步提高发动机的热效率,发挥对置式结构的优点,必须对发动机尤其是配气机构的结构参数进行进一步优化.

Thermodynamic Simulation of Cam Engine with the Counter-position

To evaluate the performance of cam engine with the counter-position placement,such a thermodynamic model based on the kinematic and dynamic analysis is developed and the corresponding program with the Runge-Kutta method is established.The results indicate that: The working principle and structure design of the special sapce engine is feasible.Then,as to further improve the thermal efficiency of the counter-position placement cam engine and exercise the engine structural advantage,the structural design param...
