| Abstract: | The vibrational response of a flexible beam excited by a moving rigid body is considered.The numerical solution and Experimental results are given in the case of simple spring supported beam.Then the optimal control scheme to suppress the vibration in the fiexible beam is proposed.The corresponding simulation and experiment are also carried out.All the experimental results agree well with the analytical and simulation results. |
