摘　　要：往复泵自生增压系统是一种新型的轨姿控发动机增压系统,根据系统的工作原理,建立了考虑传热过程的自由活塞往复泵模型以及增压系统仿真模型。针对该系统进行了动态特性仿真,获得了增压系统启动特性以及往复泵的热特性。结果表明,所建立的模型能够较好地反映增压输送过程,为系统和组件设计提供重要依据。Reciprocating pump pressurization system is a new type of orbit attitude control engine self-pressurization system.Based on the working principles of the pressurization system,the dynamic model of thermal reciprocating pump and pressurization system are established.Then the system is simulated for starting characteristic and thermal performance of the reciprocating pump.Simulation results show that models can reflect pressurization transport process,which provides an important basis for the design of components and system.
