本文将结构传递函数概念引入模态综合技术之中,提出了一种有利于实验模型的模态综合解案。文中通过结构传递函数导出了结构高阶剩余模态,为实验模型引入模态综合之中奠定了基础。同时,本文进一步讨论了将实验模型引入模态综合之中所必然出现的转角模态问题,并采用曲线拟合技术解决了这一问题。 In this paper, the concept of structure transfer function is introduced into the modal synthesis technology, and a modal comprehensive solution that is favorable to the experimental model is proposed. In this paper, the structural high-order residual modes are derived through the structure transfer function, which lays the foundation for the introduction of modal synthesis in the experimental model. At the same time, this paper further discusses the corner modal problems that will inevitably occur when the experimental model is introduced into the modal synthesis, and uses curve fitting techniques to solve this problem.
