航空激光产品的密封设计研究
|
摘要
航空激光产品对密封性能有严格要求,密封性能的优劣将直接影响航空激光产品的性能与使用寿命。基于航空激光产品密封设计缺少理论指导的现状,通过调研、试验和理论研究,从密封件选材、构型选择、沟槽尺寸确定、密封螺钉排布四个方面提出航空激光产品密封设计的原则和依据,并从固定螺钉装配和密封件装配两个方面总结航空激光产品密封结构的装配工艺,可以为提高航空激光产品的密封可靠性提供参考。
Aviation laser products have strict requirements for sealing performance,and the sealing performance will directly affect the performance and service life of aviation laser products.In accordance with the lack of theoretical guidance on the sealing design of aviation laser products and through investigations,experiments,and theoretical studies,the principles of seal design for aviation laser products were proposed from the aspects of material selection,configuration selection,groove size determination,and sealing screw arrangement.The assembly processes of the sealing structures of aviation laser products were summarized from the aspects of the setscrew assembly and sealing element assembly.These findings can provide reference for improving the sealing reliability of aviation laser products.
