摘要
针对修改结构局部刚度和质量参数、使结构某阶固有频率与局部振型分量满足给定设计要求的动力修改问题提出了一种求解方法,导出了质量与刚度参数修改结果的通解形式。
This paper presents a method for modifying the local stiffness and mass parameters of a structure so that the structure will freely vibrate at a prescribed frequency with a partially prescribed modal shape. The general expression for the modification results of mass and stiffness parameters is derived as well.
