摘要

摘要: 通过多学科动力学建模方法研究,利用AMESim建立了隔舱式贮箱推进剂输送系统机械、液流与控制动力学模型,并对不同工况下推进剂输送系统动态特性进行数值仿真,获得了隔舱式贮箱推进剂动态变化、各个隔舱的推进剂消耗率及质心位移等结果.仿真结果显示隔舱总体布局与初始容积分配、隔舱连通结构、飞行轨迹等均对隔舱式贮箱推进剂动态变化产生影响,所建立的模型可应用于隔舱式贮箱总体及结构设计.

Abstract: According to the research on the method of multi-subjects dynamic modeling, an AMESim mechanical, hydraulic and control dynamic complicated model of propellant feed system based on the compartmental tank was established, and then numerical simulation was made on the dynamic characteristics of the propellant feed system under different working conditions. The results of dynamic change of the propellant, the comsumption rate and the centroid displacement of the propellant were obtained. The simulation results show that the dynamic change of the compartmental tank propellant is influenced by the compartments general layout, initial compartments volume, structure design, flight trajectory and etc, so the simulation model can provide guidance to improve compartmental tank overall and structure design.
