摘　　要：往复型密封件是影响飞机安全和可靠性的重要部件,与国外完善的评价标准体系相比,国内往复型密封件性能考核标准极度匮乏,尤其是关键的动密封性能和抗挤出性能评价标准。该文详细分析了往复型密封件所处的复杂工况,提出了静密封性能、动密封性能以及抗挤出性能评价技术及方法,并给出了相关夹具的结构和原理。The reciprocating seals are one of the most important parts in aircrafts. Compared with the architectonical evaluation standard system abroad, domestic evaluation standards on seals are deficient, particularly on dynamic sealing and anti-abrasion. The complicated working condition is demonstrated. The evaluation techniques and methods on static sealing, dynamic sealing and anti-abrasion are given. The structure and principles of the test fixture are pointed out.
