摘要

标量传递率函数描述了多自由度系统中两个自由度的响应之间的关系，随着应用范围的延伸，近年来标量传递率逐渐受到了重视。本文从串联系统出发，证明了多激励作用下多自由度系统中标量传递率在某些条件下具有不变性，提出了该性质的统一的适用模型，并通过数值方法验证了结论的正确性。在振动台模型实验中的应用表明，该性质可以在实际问题中起到指导作用。

Abstract

Scalar transmissibility, which attracts more and more attention in recent years, describes the relationship between responses from two positions of one multi-degree of freedom (MDOF) system. The invariability of scalar transmissibility in MDOF system derived by multiple loads is proved in this paper, and the result is further extended to one unified model. A numerical experiment is performed to verify the analytical result, and then the application in vibrating table model test indicates that this property would be helpful for dealing with practical problems.
