摘　　要：以某火箭发射场新型液氧推进剂地面加注系统为对象,将整个系统简化为地面储罐、箭上贮箱、输送管路,分别建立热力学模型,并依据边界条件耦合分析,实现了加注过程的瞬态仿真。针对液氧加注过程开展了计算分析,并就影响加注性能的主要因素开展了变工况分析与讨论。The thermodynamic performance of a certain new-style liquid oxygen ground fueling system is investigated,and the complex fueling system is simplified as ground fuel tank,propellant tank of the rocket,and the transferring pipelines. To achieve the transient simulation,different models aiming at different subsystems are constructed,and all the models are coupled through the inherent boundary relations. By this approach,the fueling performance of the cryogenic filling process could be predicted. The behaviors associated with the liquid oxygen filling process is simulated,and also several factors,which may exert influence on the filling rate,are analyzed and discussed.
