为了准确理解螺栓结合部静态特性，基于结合面基础特性建立了螺栓单元结合面解析数学模型，提出了一种等效分步载荷解析算法，可以实现在结合部承受切向载荷时，无需考虑载荷间耦合关系就能对结合部力平衡非线性隐含积分方程组进行快速准确求解。采用自行设计的螺栓结合部切向加载装置进行了结合部扭转和剪切加载试验。试验与解析结果均表明，在切向载荷不超过最大静摩擦力的情况下，螺栓结合面切向变形与外载荷成线性关系。解析与试验结果的一致性验证了模型的正确性，为机械结合面静态特性分析提供了理论和试验支持，求解算法可方便地将结合面研究成果应用于工程实践。

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.
