摘　　要：低温吸附床是低温吸附式化学激光器压力恢复系统的核心部件。为了减轻吸附床壳体自重,本文采用ANSYS有限元分析方法,探索采用低温铝合金材料代替不锈钢制作吸附床壳体和封头的设计方法和优化方案。研究结果表明,低温铝合金材质吸附床的强度和真空性能均能达到设计要求,为采用轻质材料设计低温吸附床开辟了新路径。The low-temperature adsorption bed is an crucial part for the pressure recovery system of the chemical laser.In order to reduce the weight of its shell,this paper uses the finite element analysis method to explore the design method and optimization scheme to make adsorption bed shell and lid with low-temperature aluminum alloy material instead of stainless steel.The results show that the strength and vacuum condition of the aluminum alloy material adsorption bed have both met the design specifications,opening a new approach to design the low-temperature adsorption bed for the use of lightweight material.
