抄録

This paper proposes a method improving accuracy of force identification and contribution analysis in Transfer Path Analysis (TPA). TPA is a technology for solving the noise and vibration problem.The Matrix Inversion Methodisanapproachto force identification. The Matrix Inversion Methodis estimated the excitation force by the product of actual working acceleration and an inverse matrix of accelerance. However, there is a problem that error in the matrix of Accelerance or the matrix of acceleration propagate to identified force. Therefore, the Matrix Inversion Method is needed to have much accuracy. This paper proposes a new force identification method by using strain measurement. The method estimated the force using the strain Frequency Response Function (SFRF) instead of acceleration. A numerical simulation is conducted to compare the results by the proposed method with the conventional method.
