| Outline of Final Research Achievements |
In the evaluation of noise and vibration for mechanical structures, the peak value of the time response due to the input such as the shock is sometimes important. The applicant expanded sensitivity analysis to the time domain that had ever been applied in the frequency domain, and presented the sensitivity analysis for the time domain data to reduce the peak in the transient response. The repeatability of the input is required, and the input property such as frequency component can be unknown. In this research the validity of the presented approach is confirmed, and the sensitivity is expanded to the stiffness or the damping as well as the mass addition. The application to the bending vibration of the panel structure is examined and the sensitivity with the strain measurement is presented. It is also investigated that the relation between the sensitivity and the contribution
