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.
