Abstract
Pipe joint is an important component of high-pressure air system.In order to improve the tensile performance of the pipe joint of 40 MPa high pressure air system,a"maintenance-free"sleeve pipe joint is proposed to replace the traditional joint.Firstly,theoretical analysis and modeling are carried out from the point of view of drawing force.On this basis,simulation analysis and test verification are carried out to obtain the drawing mechanical characteristics of pipe joints,and the influence law of preten-sion force is obtained.The results show that when the nozzle thickness increases from 1.5 mm to 3 mm,the drawing force increases from 23.9 kN to 34.7 kN by 45.2%;When the amount of clamping increased from 0.1 mm to 0.22 mm,the drawing force increased from 30.4 kN to 43.9 kN.an increase of 44.4%.The variation of drawing force of different materials of stainless steel on the sleeve is 0.4%.The loading of preload force can be divided into three stages which are preload,elasticity and yield.The research results pro-vide a useful reference for the further development of the jacketed pipe joint of high-pressure air system.关键词
