Abstract :
The gun brings with acute vibration during its shooting, which greatly impacts gun´s firing accuracy and reliability. If vibration response has been tested and analyzed when the gun shooting, gun´s dynamic characteristic would be obtained which can afford important references for gun´s optimization and technology improving. The paper designs the testing system for gun´s shooting vibration, according to the test state and requirement during gun´s shooting. With the problem of noise interference inside the signal, wavelet threshold de-noising is adopted to decrease noise when the principle of heuristic threshold and improved threshold function are used. Then the characteristics in time and frequency domain are enhanced.
