摘要
针对于常重力下矩形贮箱类液固耦合系统受到俯仰激励情形 ,本文通过两种不同形式的Lagrange函数建立了系统耦合动力学方程 ,研究了该耦合系统在随机激励下的响应 ,求得波高响应的功率谱及均方值。对于一个算例 。
By means os two different kinds of Lagrangian functions,the dynamic equations of the coupling system containing a structure to which a rectangular tank partially filled with liquid is attached,and which is subjected to a pitch excitation in the case of normal gravity are established.The response of the coupling system subjected to a random excitation is analyzed.The power density and the mean square of wave_height response in the linear sense are obtained.Finally,the dynamic characteristics of the coupling system are discussed through a computational example.
