“…It was found that the stress was minimum during transverse intermediate tightening; Li Y [2] proposed a generalized mathematical model for accurately assessing the residual tension of bolts based on the deformation coordination equations and the elastic interaction theory; Zhou Y [3] optimized the assembly of a single thermal cell by using an improved differential evolution algorithm to optimize the number of screws, the screw positions, and the order of tightening. Wang Y [4] proposed a digital twin-based process planning method for aero-engine bolt tightening and used ultrasonic waves to detect the remaining preload of the bolt after tightening; Miao R [5] conducted field tests on three kinds of fixtures and tightening sequences, and also simulated the bolt tightening process using a finite element model. The results showed that the longer the fixture and the more the bolts are arranged, the higher the degree of nonlinear interaction; Sagheb K [6] designed an experimental method to measure the preload force and the tightening torque required to overcome the thread friction of the seeded screw complex, and the results showed that the average preload force decreases with the increase of the number of repetitions; Yu Q M [7] designed a new measuring device to study the torque during tightening and the preload force during the tightening process.…”

In order to explore the fastening scheme of screw sets in electronic components, the workbench of ANSYS finite element analysis software is utilized to establish a simulation model for the process analysis of screw sets. Using the thread preload as the constraint, Workbench is utilized to explore the effects of different tightening sequences and the number of tightening times on the maximum stress of the screws. The simulation results show that 1-3-4-2 can make the screws bear uniformly and the maximum stress is the smallest; the increase in the number of screwing times tends to decrease and then increase the maximum stress of the screws, which can be used by the finite element analysis software to provide a reference for the actual fastening situation.

Aviation components play an important role in national defense and aviation development. Bolt connections are widely used in the assembly of aviation components, due to their simple structure and convenient disassembly. In addition to the impact of elastic interaction, the gap between the tightened parts also makes it very difficult to obtain a uniform bolt load, to achieve the required tightness during the tightening process. However, the impact of elastic interaction can be reduced by selecting the best tightening sequence, and the optimal tightening sequence of aviation components under different gaps can be predicted by constructing a neural network surrogate model. Based on the predicted optimal sequence, the elastic interaction matrix corresponding to the sequence can be obtained. In order to obtain a uniform preload, the initial load of each bolt is calculated according to an elastic interaction matrix. This research has improved the tightness of aviation components and the real-life efficiency of tightening process planning.

The anti-slip performance of cable clamps is one of the important structures to ensure the safety of suspension bridges, and there is currently limited research on the influence of temperature. by using validated meteorological data, an ABAQUS thermal coupling model is established to obtain the steady-state temperature field for a representative period and apply it as a mapped field to analyze the stress results of the cable clamp-main cable structure. The analysis concludes that the derived analytical solution in this study is close to the numerical solution of the finite element method, with a maximum error of 4.2%, meeting the requirements of practical engineering. The increase in temperature of the screw itself reduces the pre-tensioning force, while the increase in structural temperature, when the screw does not experience temperature variation, can actually increase the friction force of the cable clamp to some extent, which is beneficial for improving the friction resistance of the cable clamp. During the installation of cable clamps, it is recommended to perform it at low temperatures, and the surface of the screw can be thermally insulated to maximize the increase in friction force caused by structural temperature rise.
