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。
In this paper, we propose a new method to establish a system of dynamic equations by using two different forms of Lagrange functions. The dynamic characteristics of a rectangular tank-type liquid-solid coupling system under pitching excitation are analyzed. The “jump” “And” lag "and other nonlinear systems have kinetic phenomena.
