中文摘要:
      本文针对耐高温动态热密封组件中的常用元件弹性支架编织弹簧,研究了其压缩量、装配方式、热暴露温度等参数对其弹性性能的影响,并讨论了编织弹簧高温弹性失效的原因。研究结果表明,合金的氧化是编织弹簧高温回弹率降低的主要原因,在低于800℃、压缩量小于50%的服役条件下,编织弹簧的回弹率不小于95%,在航天热密封领域有广阔的应用前景。

英文摘要:
      In this paper, the effects of the compression, assembly and heat exposure temperature on the elastic properties of the braided spring using as the elastic support of thermal barrier seals were investigated systematically, and the reason for elastic failure of the braided spring on high temperature was also discussed. The results show that the oxidation of alloy is the main reason for reduced resiliency of braided spring on high temperature, and the resiliency of braided spring is more than 95% when the compression is less than 50% below 800℃, which indating that the as-prepared braided spring may have broad application prospects in aerospace thermal barrier.
