机械关节的体现是机构设计过程中一项要求很高的工作。在这种情况下，评估几何偏差对机械接头行为的影响尤其重要。本文提出了一种考虑形状偏差的机械接头间隙外壳估计方法。这种方法的新颖之处在于能够分析考虑多对配合表面的机械接头的行为。该方法在棱柱形接头和圆柱形接头上的应用证明了该方法对于具有多对接触表面的不同类型接头的多功能性。此外，将该方法应用于两销两孔组件的公差分析的结果证实了在公差分析以及机械接头和机构设计中考虑形状偏差的重要性。
The embodiment of mechanical joints is a demanding activity during the design of mechanism. In this context, particularly the assessment of the effects of geometrical deviations on the behaviour of the mechanical joint is of strong importance. This paper presents an approach to the gap hull estimation for mechanical joints considering form deviations. The novelty of this approach lies in the ability to analyse the behaviour of mechanical joints considering multiple pairs of mating surfaces. The application of this method to a prismatic as well as to a cylindrical joint prove the versatility of the method regarding different kinds of joints with multiple pairs of contact surfaces. Moreover, the results of the application of this approach to the tolerance analysis of a two-pin-two-hole assembly confirm the importance of considering form deviations in the tolerance analysis and in the design of mechanical joints and mechanism.
