Abstract
CAE technology improves, and a variety of optimization techniques begin to be introduced into the design of the machine structure. One purpose of the optimization techniques is to propose the measures idea against the engineering problem. However, it is difficult to propose the measures idea efficiently in a present optimization technique (for instance, sizing optimization) when thinking about the vibration problem of the structure. Moreover, there were problems in the formulation of the rigidity of the uniting part and the normalization of sensitivity in the sensitivity analysis by the transfer function synthesis method. Therefore, to establish the method of efficiently proposing measures against the vibration problem, it proposed the sensitivity analysis using the eigenvalue and the eigenvector of the stiffness matrix. It is possible to propose the measures idea that the designer understands easily by this method.
