装配偏差对飞机液压管路密封性能的影响
Influence of assembly deviations on the sealing performance of aircraft hydraulic pipelines
摘要
Abstract
To investigate the influence of assembly deviations on pipeline sealing performance,a finite element model was established based on the torque-tension relationship.The influence of three assembly deviations(axial,radial,and angular)acting individually on the sealing performance of pipeline connectors was analyzed,and the coupling influence of these three assembly deviations on the sealing performance of pipeline connectors was studied through orthogonal experiment.The results indicate that under single deviation conditions,negative axial deviation,radial deviation,and angular deviationall reduce pipeline sealing performance.When the three assembly deviations are coupled,the sealing performance decreases.Negative axial deviation and angular deviation have significant influences on pipeline sealing performance,while the influence of radial deviation is relatively small.Therefore,in practical engineering,negative axial deviation and angular deviation should be strictly controlled,and positive axial deviation and radial deviation should be minimized as much as possible.关键词
