摘要
本文应用连续系统稳定性理论,处理粘性不可压缩流体所支持的平衡浮体的非线性稳定问题,其中考虑到浮体的方位角和质心位置以及流体速度的非线性扰动,给出了各种尺度的非线性稳定、渐近稳定判据及不稳定判据。
The problem of nonlinear stability of equilibrium floating bodies on viscous liquid is discussed by using the stability theory of continuous system. The nonlinear disturbances being considered involve the orientation angles of the floating bodies, location of the centre of mass and the velocity of fluid. The criteria for nonlinear stability, asymptotical stability and instability with respect to various kinds of distance are given.
