| 摘 要： | 本文以一种新方法建立了水平激励下圆柱贮箱类液固耦合系统的动力学方程。利用两类完全不同的Ｌａｇｒａｎｇｅ函数来描述液体子系统和结构子系统的运动，联立可得耦合系统的动力学方程。通过数值仿真发现，在一定的激励幅值和频率下，该耦合系统会出现零位漂移、分叉等非线性动力学现象。

| Abstract: | The paper presents a new method to establish the dynamic equations of the coupling system containing a structure to which a cylindrical tank partially filled with liquid is attached,and which is subjected to a horizontal excitation.Based on two different kind of Lagrange function,the motion of liquid subsystem and structure subsystem are described.Finally,the nonlinear coupled dynamic equations of the coupling system are established.Through numerical simulation,it is found that nonlinear dynamic phenomenon,such as zero drift and bifurcation,will appear at certain range of excitation amplitude and frequency in the proceeding coupling system. |
