ANALYSIS ON DYNAMIC CHARACTERISTICS OF THE LIQUID-SOLID COUPLING SYSTEM WITH LIQUID IN A RECTANGULAR CONTAINER UNDER PITCHING EXCITATION
【摘要】 应用本文提出的综合运用两类不同形式的Lagrange函数建立系统动力学方程组的新方法 ,分析了俯仰激励下矩形贮箱类液固耦合系统动力学特性 ,观察到了幅频响应曲线中的“跳跃”和“滞后”等非线性系统所具有的动力学现象。
【Abstract】 The nonlinear dynamic characteristics of the coupling system consisting of a structure to which a rectangular tank partially filled with liquid is attached and which is subjected to a pitching excitation is analyzed by the present method using two different kinds of Lagrange functions to establish coupled dynamic equations of the system.The‘jump’and‘lag’in the amplitude-frequency response curve which are the dynamic phenomena of nonlinear system are observed.
