摘要
分析了变刚度半主动控制结构的减振原理;基于单自由度结构和多自由度结构体系的仿真分析,对比分析了变刚度半主动控制结构的减振效果。通过MATLAB程序对结构动力方程的求解,基于程序可视化结果表明,变刚度半主动控制结构具有较好的减振特性,是结构振动控制一个很好的发展方向。在明确变刚度半主动控制结构减振效果的基础上,探讨了减振装置的安装位置,通过算例对比,基于成本及施工方便的考虑,得出最佳安装位置。
In this paper,active variable stiffness damping control structure theory is analyzed.Based on single degree of freedom structure and multi-degree of freedom structural system of the simulation,comparative studyon active variable stiffness control of the damping effect of the structure is carried out.Through the MATLAB program on the structural dynamic equations,the results show that the semi-active variable stiffness control structure has good damping characteristics,and is a good direction of vibration control.Based on the effect of vibration reduction,the installation location of the damping device is discussed.and the optimal installation location is obtained considering the cost and convenient construction.
