高压气瓶结构设计与仿真及试验研究

Structural Desig and Simulation and Experiment Study of High Pressure Refrigeration Cylinder

高压制冷装置通过管路给红外探测器供气制冷,将探测器元件冷却至低温或深低温,使热成像系统正常工作。高压气瓶为高压制冷装置储存和提供高压气体,是高压制冷装置的主要组件。详细阐述了高压气瓶的结构设计方法并进行不同载荷的仿真试验,同时根据拉梅公式对气瓶的爆破形态进行理论分析,最后通过瓶体爆破试验加以验证。

Through pipeline,high-pressure refrigeration device supplies gas to infrared detector cooling the detector elements down to low or lower temperatures,which enables the thermal imaging system to run normally.High-pressure gas cylinder,the main component of the high-pressure refrigeration device,stores and provides the device with high-pressure gas.This paper elaborates the structural design method of the high-pressure gas cylinder and carries out the simulation tests of different loads.Meanwhile,the blasting form of the gas cylinder is theoretically analyzed according to lame formula,and verified by the blasting test of gas cylinder body.
