摘　　要：对应用于低温加注系统的氧氮过滤器进行滤芯优化,以提高过滤器特别是滤芯的强度和可靠性。在保证滤网骨架外形尺寸、通流面积均不变前提下,通过结构设计改变通流孔的形状、数量、分布,同时对滤网、滤网骨架、固定件(压条+压环)之间的焊接要求进行细化,明确焊点间距、分布要求,明确纵向固定件两端与横向固定件间的固定要求,提出温度循环和双向液流冲击的滤芯验证措施,对优化改进前后的滤芯强度的对比数值模拟及历次任务的使用均表明滤芯优化的有效性。The optimization design of tile filter used in tile ClyogeniC propellant filling system is discussed in this paper. Under tile condition of inaintailling tile outline dilnension and flow area of filter, tile opfilnization designS include tile change of tile hole in tile ffalnework （ number, dimension, location） ; tile improvement of tile welding requirement between ffalnework, net and fdsten piece; tile clarification of tile space and location of tile welding pot, and tile fixation between tile axial fdsten piece and tile axial fasten piece. Then tile verificafiOnS such as temperalure cycle test aM double way impulsion test were proposed and completed. Tile nulnerlcal simulation results and tile use of previous missionS indicate tile effectiveness of the optimization.
