This research is focused on a procedure to optimize the reinforcement point for dynamic structures. In the design optimization process, the degree of optimization is dependent upon the initial starting point design configuration. A poor choice of initial reinforcement point will not yield optimization design results.
The optimization objective function is to raise the modified natural frequency of a target mode to be as high as possible. The point, where the natural frequency of the target mode becomes a maximum value, is the optimal solution under given constraints.
Especially, it is very hard or impossible to construct the finite element models for the most real object structures. But for the attached substructure, relatively simple shape such as a beams can be generally used. So, experimental data from the object main structures can be used, unlike the attached structures where the FE data is used.
