充液系统刚-液耦合动力学功能型拟变分原理
Quasi-variational principle of rigid-liquid coupling dynamics in liquid-filled system
摘要
Abstract
With the increase of the capacity of launch vehicles , lifespan of satellites and the complexity of deep space missions increase , the mass proportions of liquid propellant in spacecrafts are enhanced accordingly .Liquid-filled system dynamics is a universally concerned topic in the theoretical field .The coupling between the quasi-vari-ational principle of fluid dynamics and the quasi-variational principle of rigid dynamics , along with the quasi-varia-tional principle of rigid-liquid coupling dynamics in liquid-filled system were researched by using the work and en-ergy transfer principle and energy conservation law .In this paper , the coupling mechanism of the liquid-filled tanks of spacecrafts is discussed , providing theoretical support for establishing the equivalent mechanical model of liquid large amplitude sloshing .关键词
