| Abstract: |
| This paper presents a method to design a combined structure subject to multiple naturalfrequencies requirement by optimizing the connecting component between the substructures.The residual attached modes are added to the kept ones for each substructure to reduce thedegree of freedoms in the combined structure reanalysis. It improves the accruacy and effi-ciency of the calculation,The shifting technique is used for the substructure which has rigidbody modes.Examples show the effectiveness of the method given by this paper. |
