摘要
本文讨论微重力场中带球面隔板的球腔内液体晃动问题。选择Legendre函数作为Ritz方法的基函数,计算液体的自由晃动及腔体横向振动激励的受迫振动。计算结果表明,自由晃动频率随隔板位置的下降而趋于升高。液体晃动的动力学效应可用等效的质量—弹簧系统模拟。
The paper discusses the liquid sloshing in a spherical container with spherical baffle under low-gravity environment. The Legendre's functions are used as the base functions for Ritz's method to caloula'e the free sloshing and force sloshing excited by the transverse oscillation of the container. The numerical calculation shows that the frequency of free sloshing increases as the position of the baffle is lowered. The dynamical effect of the liquid sloshing motion can be simulated by an equivalent mass-spring system.
