Abstract Loosening of threaded fasteners is a key failure mode, which mainly caused by the slippage and friction behaviors on thread bearing surfaces, will affect integrity reliability products. Numerous scholars have conducted research loosening fasteners; however, comprehensive reviews been scarce. In this review article, we define as loss preload divide it into non-rotational rotational loosening. The causes mechanisms are summarised. Some essential topics regarding under transverse...
The real contact area and separation between rough surfaces are significant parameters in sealing, tribology, lubrication. However, it is challenging to experimentally observe the behaviors because materials of usually non-transparent not accessible for direct visual observation. In this study, X-ray computed tomography was used directly measure surfaces. three-dimensional surface pairs made aluminum polycarbonate were measured. addition, finite element models developed simulate same pairs....
In the context of accelerating new technological revolution and industrial transformation, issue talent supply demand matching has become increasingly urgent. Precise is a critical factor in expediting implementation innovations. However, traditional methods relying on interpersonal networks for ability collection, transmission, suffer from inefficiency are often influenced by subjective intentions intermediaries, posing significant limitations. To address this challenge, we propose novel...
Sufficient preload in a bolted joint is key to ensuring the reliability of mechanical products; however, under vibration, decrease often occurs. The mechanism has not yet been fully clarified. In this study, finite element models joints with and without helix angles were constructed study transversal vibration. Based on analysis results, new cause decrease, denoted as stress release redistribution, was discovered explained detail. caused by cyclic plasticity deformation rotation loosening...
The influences of the micron bondline thickness, temperature, and loading rate on tensile strength adhesive joints were studied for precision structures, fractured surfaces analyzed by infrared imaging SEM methods. testing results show that increases then linearly decreases with increase thickness; peak is always acquired at thickness around 30 μm; maximum up to 28.6% as from 10 μm 1 mm/min; more than 33% finally reaches a closed value different thicknesses temperature rises −30 110 °C....
Lattice structures have excellent mechanical properties and can be designed by changing the cellular structure. However, computing scale is extremely large to directly analyze a large-size structure containing huge number of lattice cells. Evaluating equivalent instead complex geometry such cells feasible way deal with this problem. This paper aims propose series formulas, including critical structural material parameters, fast evaluate structures. A reduced-order model based on finite...
Abstract The assembly process of aerospace products such as satellites and rockets has the characteristics single- or small-batch production, a long development period, high reliability, frequent disturbances. How to predict avoid quality abnormalities, quickly locate their causes, improve product efficiency are urgent engineering issues. As core technology realize integration virtual physical space, digital twin (DT) can make full use low cost, efficiency, predictable advantages space...
The distributed assembly hybrid flow shop scheduling problem (DAHFSP) is a type of problem, and each can be regarded as shop. In processes for complex products such satellites missiles, transportation time worker assignment have important effects on production scheduling. Based real situations, this study proposes novel DAHFSP considering time, aiming to minimise the makespan imbalance degree workloads. First, solve these problems, we construct mathematical model design two-layer chromosome...
This paper proposes a tolerance analysis method of annular surfaces considering form errors and local surface deformations. Specifically, are properly considered based on skin model shapes. Local deformations calculated Conjugate Gradient-Fast Fourier Transform (CG-FFT) method, which is classic Boundary Element Method (BEM). Based thereon, conducted Monte Carlo simulation, efficiency the process also demonstrated.
