“…In order to obtain experimentally the bolt clamping force (bolt pre-load) in a joint, there are different kinds of methods such as torque wrench method [34], angle control method [35], ultrasonic method [36,37] and load cellstrain gage method [13,14,[38][39][40]. In this research, owing to its better accuracy compared to other methods, the load cell and strain gage method was applied.…”

This study investigates the variation of clamping force and its concomitant effects on the performance of bolted double lap joints subjected to longitudinal loading. Two different amounts of clamping force were applied to bolted double lap joints made of Aluminium 2024‐T3, and variations of clamping force were measured under the application of longitudinal loading. Finite element modelling was also performed to compare with experiments. The results unanimously revealed a gradual initial reduction of clamping force followed by a significant increase as the longitudinal load was increased. Also affected, was the load transfer mechanism in the joint resulting in variation of friction force between the plates, but in a different trend compared to clamping force. Finally, the key parameters have been discussed and highlighted pertaining to the performance of the joint.

“…For parametric modeling, a large number of works are also done with the emphasis on single mechanical characteristic of bolted joints. For instances, Alkatan et al 18 discussed the axial stiffness of bolted joints; Chakhari et al 19 investigated the tension and compression stiffness of bolted joints; Hoang et al 5 focused on tension stiffness and shear stiffness of bolted joints. However, bolted joint has stiffness on seven directions.…”

To accurately describe mechanical characteristics in the modeling and analysis of bolted joint structure in complex mechanical system, this article investigates on the equivalent parameters of mechanical characteristics (tension and compression stiffness, bending stiffness, shear stiffness, and torsion stiffness) of bolted joints by theoretical derivation and provides an effective modeling approach with thin-layer element theory and equivalent parameters as well. First, the equivalent parameters of mechanical characteristics of bolted joints are achieved. And then the finite element model of bolted joint is established by equivalent parameters, called as parametric modeling method. Based on two cases of study, the mode analyses of parametric finite element models are implemented with dynamic test data to validate the developed parametric finite element models of bolted joints with the equivalent parameters. It is shown from the investigations that parametric finite element models have higher precision than finite element model in structural dynamic analysis because the analytical results based on parametric finite element models are closer to test data. It is fully demonstrated that the equivalent parameters may effectively simulate the mechanical characteristics of bolted joint structures, and the parametric modeling approach with equivalent parameters is efficient and high fidelity for bolted joints in complex machinery due to high precision in mode analysis. The efforts provide an effective modeling method for simulating the mechanical characteristics of bolted joints and designing bolted joint structure in complex machinery.

“…10 In fact, bolted joint structure generally contains five kinds of stiffness: tensile stiffness, compressive stiffness, transverse bending stiffness, shear stiffness, and torque stiffness. Although the rapid development of FE technique for the design analysis of one bolted joint, [6][7][8] no related modeling approach has been proposed for the analysis of different stiffness of bolted joint based on FE technique yet.…”

To establish accurate finite element (FE) model of bolted joint structures of aeroengine stator system (casings), this work implements the parametric FE modeling and updating of bolted joints of aeroengine stator system with multi-characteristic responses (multi-object). Firstly, the parametric FE modeling approach of bolted joint structure was developed based on the thin layer element method. And then the FE model updating thought of aeroengine stator system was developed based on the probabilistic analysis method. Finally, the parametric modeling and updating of the bolted joints of aeroengine stator system with multi-characteristic responses was completed by the optimization iteration calculation of objective function based on the proposed methods and the static stiffness testing data. Through the parametric modeling of bolted joint structures based on the thin layer method, the complexity of FE model of aeroengine casings with many bolted joint structures is reduced. As shown in the FE model updating of casings with multi-characteristic responses analysis, the static stiffness from the updated model are very close to the test data, in which the maximum relative error decreases to 3.9% from 30.52% and the others are less than 3%, so that the design precision of aeroengine stator system with the many and wide variety of bolted joints gets a great improvement. Moreover, the proposed methods of parametric modeling and model updating for multi-characteristic responses are validated to be effective in the simulation and equivalent of the mechanical characteristics of bolted joints in complex systems like aeroengine stator system.
