Thismodel is calculated by using the numerical m ethod. The response of themodel is analyzed, and theAmplitude frequency Curves are plotted, and the greater fluence of the pulse is found in the low frequency. The parameters of the model are researched, and the Amplitude frequency Curves under various damping ratio and under various exciting vibration force are compared respectively.
