摘要
为提高起爆器在极限环境中的密封性,设计了一种可以用于激光焊接的不锈钢密封片,将其与壳体激光焊接,可实现起爆器的金属密封;密封片设计"米"字型消弱槽的结构,采用数值计算方法建立了密封片消弱槽的设计与计算方法,同时,对该设计进行了起爆器发火试验验证。试验结果表明:起爆器发火后无金属碎片产生,提高了产品的传火可靠性。
To improve the sealing property of initiator in extreme environment,the design and calculation of a stainless steal sealing disc used in laser welding was proposed.Through welding the sealing disc to the shell of initiator by laser beam,the whole metal sealing of initiator would realized.On the surface of sealing disc,the"米"type weaken groove was designed,the calculation method of the strength of sealing disc was established and verified by ignition test of initiator.The test result show that no metal fragments exist after ignition,the reliability of ignition is improved obviously.
