IMPROVEMENT OF TRANSIENT VIBRATION BY SENSITIVITY ANALYSIS

Transient vibration occurs out when the force acting on a system sudde nly changes. Overshoot of the response is one of the evaluation points of the transient characteristics. However, it is difficult in a multi -degree-of-freedom system to reduce the overshoot without increasing d amping. That is because so many vibrational components appear at once and interfere with each other. Sensitivity analysis has been used to i mprove eigenfrequencies, eigenmodes or transfer functions, but few app lications are known in the field of time domain response. In this pape r, improvement of the overshoot in transient vibration by sensitivity analysis is discussed.
