摘要/Abstract

摘要： 为规避传统制冷气瓶给导弹电子器件带来的安全隐患，设计一种绝缘气路接头。利用三维机械设计软件Solidworks完成绝缘气路接头三维设计，利用有限元分析软件ANSYS对结构进行了气密性仿真，并进行实物导电试验和通气试验。结果表明：该气路接头在极限气压下不漏气，且在导电实验和气密性实验中未出现导电和漏气现象；该气路接头同时具有绝缘性和气密性，能够规避弹上气路存在的安全隐患。

Abstract: An insulated gas circuit joint is proposed to avoid the potential safety hazards brought by traditional refrigeration gas cylinders to missile-borne electronic devices. It is designed by using three-dimensional design software Solidworks.The airtightness of joint structure was simulated by using ANSYS software, and a real gas circuit joint was made for conductivity and ventilation experiments. The simulated results show that the gas circuit joint does not leak under the limit pressure, and has no electric conduction and air leakage in the electric conduction and air tightness experiments. Simulated and experimental results prove that the insulated gas circuit joint has both insulativity and air tightness, and can avoid the potential safety hazards of missile-borne air circuit.

Key words: short-rangeairdefensemissile, gascircuitjoint, threadedconnection, insulativity, airtightness
