For engineering structures, there is a strong need to assign natural frequencies to achieve desired dynamic performance. This study proposes a receptance-based frequency assignment method for assembled structures. Very often, the substructures involved are not allowed or are difficult to change. This method uses the links between the substructures as targets of structural modifications and determines the structural properties of the links that assign the desired frequencies cast as an optimisation problem. These links could be either simple discrete structural components such as masses and springs or complex continuous structures. Only a few receptances of the substructures are required in this method, which can be measured accurately and easily in practice. Two numerical examples are presented to show the validity of this method and its strength in dealing with complex assembled structures.

对于工程结构，强烈需要分配固有频率以实现所​​需的动态性能。这项研究提出了一种用于装配结构的基于接收的频率分配方法。很多时候，涉及的子结构是不允许的或难以更改的。此方法使用子结构之间的链接作为结构修改的目标，并确定分配所需频率的链接的结构属性，这些频率是优化问题。这些链接可以是简单的离散结构部件（例如质量和弹簧），也可以是复杂的连续结构。在这种方法中，仅需要几个子结构的接纳，就可以在实践中准确，轻松地对其进行测量。
