Abstract

Shimming position and amount have a significant influence on the weight and mechanical performance of the thin-walled product that having assembly gap during aerospace components assembly process. An analytical method for assembly-induced deformation prediction of the bolted composite joints with assembly gap was developed. The assembly-induced deformation under the preloading force was computed as bending deformation and bolt head compression deformation by evaluating whether assembly gap can be eliminated and whether the calculating point is within the conical and spherical envelope of the fastener. The proposed method was validated by the preloading experiment of three-bolt composite joints with relative error less than 10%. Then it was applied to analyse the assembly-induced deformation of a composite box structure including composite spars and skins. Under the guide of the analytical result, shimming assembly of the composite box structure was carried out. The proposed analytical method has a good application prospect to predict the assembly-induced deformation during preloading process for composite/composite joints or composite/metal joints.

含装配间隙的复合材料螺栓连接装配变形预测分析方法

在航空航天零部件装配过程中，摆振位置和摆振量对存在装配间隙的薄壁产品的重量和力学性能有重要影响。提出了一种具有装配间隙的复合材料螺栓连接的装配变形预测分析方法。通过评估装配间隙是否可以消除以及计算点是否在紧固件的锥形和球形包络内，将预紧力作用下的装配变形计算为弯曲变形和螺栓头压缩变形。通过三螺栓复合节点预压试验验证了该方法的有效性，相对误差小于10%。然后应用该方法对包含复合梁和复合蒙皮的复合箱式结构进行了装配变形分析。在分析结果的指导下，对复合材料箱体结构进行了摆振装配。该分析方法在预测复合材料/复合材料接头或复合材料/金属接头预压过程中装配变形方面具有良好的应用前景。

期刊介绍： Manufacturing industries throughout the world are changing very rapidly. New concepts and methods are being developed and exploited to enable efficient and effective manufacturing. Existing manufacturing processes are being improved to meet the requirements of lean and agile manufacturing. The aim of the Journal of Engineering Manufacture is to provide a focus for these developments in engineering manufacture by publishing original papers and review papers covering technological and scientific research, developments and management implementation in manufacturing. This journal is also peer reviewed. Contributions are welcomed in the broad areas of manufacturing processes, manufacturing technology and factory automation, digital manufacturing, design and manufacturing systems including management relevant to engineering manufacture. Of particular interest at the present time would be papers concerned with digital manufacturing, metrology enabled manufacturing, smart factory, additive manufacturing and composites as well as specialist manufacturing fields like nanotechnology, sustainable & clean manufacturing and bio-manufacturing. Articles may be Research Papers, Reviews, Technical Notes, or Short Communications.
