| 摘 要： | 通过正交试验研究了超声波焊接参数对火工品密封性和电阻的影响。试验结果表明:超声波焊接压力对于密封性和电阻的影响最大,熔接时间次之,发振位置对焊接效果影响不显著。随着焊接压力升高、熔接时间延长,焊接量会增大,更有可能导致电极的焊点损坏和插针松脱等缺陷,破坏桥路连通性并造成泄漏。

| Abstract: | The influence of ultrasonic welding parameters on leakage rate and resistance of initiating explosive device was studied, based on the orthogonal experiment. The experiment results showed that, welding pressure has the highest effect on sealing property and resistance, welding time has certain effect, while the effect of vibration location is little. With the increase of welding pressure and prolong of welding time, the welding amount would be enlarged, the defects of electrode pins loosing up during the process would exist more possible, which would induce the leakage of initiating explosive device. |
