Vibration Analysis of Flexible Arm with Trapezoidal Velocity profile

사다리꼴 속도분포에 따른 유연한 외팔보의 진동해석

The dynamic interaction between a translating flexible arm and a trapezoidal velocity profile of a cart to which the flexible arm is attached is presented. Vibration of the flexible arm due to translation is analytically solved, and the conditions for suppressing vibration is derived in terms of velocity profiles. To prove the validity of the solution and the conditions, numerical computation and experiments are camed out. Only a natural frequency of vibrating plant is needed to obtain the conditions for vibration reduction. With this results, a passive vibration regulator as an open loop control scheme can be designed and direct application to industrial plants such as overhead crane can be made.
