Numerical simulation for half-sine pulse generated by rubber waveform generator

By applying the drop testing machine to automatically simulate half-sine pulse,the calculating model was set up to describe the course of half-sine pulse generated by the rubber waveform generator,based on the basic mechanical principle of half-sine pulse generation and non-linear of the rubber waveform generation in the condition of quasi-static compress.The results showed that the curve of acceleration vs time by practical test generally tallied with that model calculated,and the model could be used to simulate and forecast half-sine pulse of shocking table board reasonably and efficiently.
