| Abstract: | Using the method of putting an electronic presure device into a shot and according to the principle of non-electric measure,it analyzed the acquired signals,set forth the designing thought of the development of shot sound signal device,entire design and structure,and explained the working principle of the presure device in shot,testing circuit and so on.After amplification,collecting samples,maintenance and the shift of A/D,the acquired signals were input into a computer and analyzed,thus measuring the dynamic parameters of the action of throwing arm on a shot in the precess of throwing a shot. |
| Keywords: | shot sound signal information feedback development of equipment tesing system dynamic test |
