“…[4][5][6][7][8] During manufacturing of a thin-walled composite part, unexpected spring-back deformation and machining-induced deformation due to internal stress release will lead to out-of-tolerance of the parts and poor mating surface conditions of the assembly interface in the assembly process. [9][10][11][12][13][14] As a result, there will be assembly gaps at the assembly interface between two assembled composite parts, such as the assembly interface between composite skin and composite spar of the aircraft wing box structure.…”

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.

PurposeThe purpose of this research is to provide a theoretical framework for complex equipment quality risk evaluation. The primary aim of the framework is to enhance the ability to identify risks and improve risk control efficiency during the development phase.Design/methodology/approachA novel framework for quality risk evaluation in complex equipment is proposed, which integrates probabilistic hesitant fuzzy set-quality function deployment (PHFS-QFD) and grey clustering. PHFS-QFD is applied to identify the quality risk factors, and grey clustering is used to evaluate quality risks in cases of poor quality information during the development stage. The unfolding function of QFD is applied to simplify complex evaluation problems.FindingsThe methodology presents an innovative approach to quality risk evaluation for complex equipment development. The case analysis demonstrates that this method can efficiently evaluate the quality risks for aircraft development and systematically trace back the risk factors through hierarchical relationships. In comparison to traditional failure mode and effects analysis methods for quality risk assessment, this approach exhibits superior effectiveness and reliability in managing quality risks for complex equipment development.Originality/valueThis study contributes to the field by introducing a novel theoretical framework that combines PHFS-QFD and grey clustering. The integration of these approaches significantly improves the quality risk evaluation process for complex equipment development, overcoming challenges related to data scarcity and simplifying the assessment of intricate systems.

“…Qiao et al 26 proposed an assembly deviation calculation method based on surface deviation modeling, using the randomness of the deviation function coefficients and random variation of three random parameters to solve the calculation problem of assembly deviation. Wang et al 27 took the geometric feature of the mating faces as the study object, analyzed the overall structure of complex products and the information requirements of each assembly design stage to construct the assembly feature information model, and then established the matching rules of feature pairs, assembly relationship, and assembly constraint instructions. Chen et al 28 focus on developing a modeling methodology to describe the relationship between the range of machining geometric tolerance and the motional domain of machine tool axe based on an improved Jacobian-Torsor theory.…”

Assembly is an essential part of aero-engine manufacturing, and the assembly quality will affect the engine’s stability and service life. Spindle inertia is an essential factor affecting aero-engine dynamic performance. Assembly can affect the spindle inertia of the aircraft engine, which in turn affects the dynamic performance of the engine. This paper proposes a transfer model of spindle inertia based on machining error transmission, studying the variation law of spindle inertia of multi-stage rotors under the influence of assembly, providing an optimized assembly method with minimized spindle inertia. The influence law of machining errors on spindle inertia is analyzed through the simulation and probability density method. The assembly results of the designed rotors verify the effectiveness of the inertia transfer and assembly model. The results show that the spindle inertia of multi-stage rotors is affected by machining errors, and the spindle inertia can be adjusted by changing the assembly methods. This paper provides a new idea for the transmission and adjustment of spindle inertia of assembly rotors.
