摘要
为提高动力吸振器在结构振动控制中的效果,提出对动力吸振器的参数进行优化分析。以工程中典型的圆柱壳为研究对象,建立动力吸振器—圆柱壳耦合振动运动方程和求解方法;以壳体均方速度最小为目标函数,运用数值优化对动力吸振器的参数进行优化分析。研究表明,优化动力吸振器的参数和布置位置可以有效降低壳体的振动均方速度。
In order to improve the vibration control effectiveness of dynamic vibration absorber(DVA), the optimization of DVA parameters is proposed in the present paper. The coupling equations of cylindrical shell and DVA are established at first, and then the method to solve the equations is deduced;Parameters and displacement of DVA are optimized to get the minimum mean-square velocities of cylindrical shell. Research shows that mean-square velocities(MSV) of cylindrical shell related to optimal parameters and displacement are much less than the value of other parameters and displacement.
