Theoretical Analysis and Test on Static Characteristics of Bolt Joints under Tangential Load
摘要
Abstract
To observe the static performance of bolt joints accurately,an analytic mathematical model of bolt unit interfacing was established based on j oint interfaces basic characteristic parameters. A multi-stage equivalent load analyzing algorithm was proposed to solve non-linear implicit integration equations quickly and correctly when tangential load was applied to the j oints,not considering the coupling relation among loads.Torsional and tangent loading tests were conducted using self-designed bolt j oint tangent loading device.The results of the tests and analyses indicate that when tangential load does not exceed the maximum static friction,the results reveal a linear relation between joint in-terface tangential deformation and external load.The consistence between the analysis and test results validates the correctness of analytic model,which provides theoretical and test evidence for investiga-ting static performance of mechanical interface,and the analyzing algorithm makes it easy to apply the j oint interface research fruits to engineering practice.关键词
