摘　　要：为解决温度-高度试验中的密封性问题并提升试验效率,本文提出了一种基于锥形结构和内外压差设计的快速封堵工装。传统的封堵方法往往需要较长时间来完成封堵过程,且难以应对极端环境中的密封需求,尤其是在高温(80~150)℃和高海拔(≥18000 m)同时要求具备的条件下,封堵效果不稳定且存在泄漏风险,导致试验周期长、成本高。而本文所提出的封堵工装能够显著提高密封性能,并将封堵时间从约3 h缩短至0.5 h,大幅提升了试验效率。该工装通过改进封堵结构,利用锥形设计和内外压差原理,确保了在高温和高海拔试验环境下的可靠密封,避免了传统方法中封堵时间长、操作复杂和密封性能不稳定的问题。To address the sealing issues in temperature-altitude tests and improve test efficiency,this paper proposes a rapid sealing fixture based on a conical structure and internal-external pressure differential design.Traditional sealing methods often require a long time to complete the sealing process and struggle to meet the sealing demands in extreme environments,especially when both high temperatures(80~150)℃and high altitudes(≥18000 m)are required simultaneously.These methods often result in unstable sealing performance and leakage risks,leading to prolonged test cycles and high costs.In contrast,the sealing fixture proposed in this paper significantly improves sealing performance,reducing the sealing time from approximately 3 h to 0.5 h,thereby greatly enhancing test efficiency.By improving the sealing structure and utilizing the principles of conical design and internal-external pressure differential,this fixture ensures reliable sealing in high-temperature and high-altitude test environments,avoiding the problems of long sealing times,complex operations,and unstable sealing performance associated with traditional methods.
