本文提出了一种确定螺栓孔间隙对复合多螺栓连接荷载分布影响的简化方法。该方法适用于具有单柱螺栓的接头，并且是先前不包括间隙影响的方法的扩展。它可以适用于单搭接和双搭接。通过三维有限元模型对该方法进行了验证，并给出了不同间隙情况下的算例。结果表明，即使很小的间隙也能显著改变关节内的载荷分布。最后将该方法应用于参数研究中，考察了不同节点参数对荷载分布的影响。(c) 2005 Elsevier Ltd版权所有。
In this paper, a simplified method for determining the effects of bolt-hole clearance on the load distribution in composite multibolt joints is presented. The method is applicable to joints with a single column of bolts and is an extension of a previous method which did not include clearance effects. It can be applied to both single-lap and double-lap joints. The method is validated against three-dimensional finite element models, and some examples of different clearance cases are shown. It is shown that even small amounts of clearance can significantly alter the load distribution in the joint. Finally the method is used in a parameter study to examine the effects of various joint parameters on load distribution. (c) 2005 Elsevier Ltd. All rights reserved.
