On the Improvement of Impulse Measurement Device and its Data Processing Method

In this paper,the improvement of a pendulum-type device for measuring sheet explosive specific impulse and its data processing method is recommended.First of all,based on the improvement of device mechanical structure,the pendulum swing angle was measured by grating testing system,which has solved the waveform distortion problem in measurement and improved the accuracy and stability of device.Then,the variation of damping coefficient along with the swing amplitude was studied by this improved device,which was verified by experimental data.Correcting method for the maximum swing angle in sheet explosive specific impulse measurement was proposed,and comparative experiment was carried out.Results show that improved measurement device and its data processing method can more accurately measure sheet explosive specific impulse.
