摘要:应用有限元分析软件ANSYS,建立了桥丝式电火工品的有限元仿真模型,对桥丝式电火工品的直流发火过程和电容放电发火过程进行了有限元分析,得出了两种情况下火工品的温度分布云图、径向温度分布曲线和桥丝与药剂交界面的温度变化曲线,并对仿真结果进行了分析讨论。
Abstract:Using ANSYS engineering analysis software, the finite element analysis model for the bridge-wire EED was set up in this paper. The finite element analysis is carried out for firing sequence on direct current firing and capacitor discharge firing condition. Radial temperature, radial temperature distribution and temperature curve at the interface of bridge-wire and ignition powder were procured and the results were discussed.
