Subjected to coupled alternating stresses and small cyclic motions, fretting wear occurs in the internal steel ropes, leading to fatigue damage and reduced service life. Studying fretting behaviour through experiments is economically costly and cumbersome. This study numerically investigated the effects of system tangential stiffness (<em>Ks</em>), Crossing Angle (<em>CA</em>), and contact load (<em>P</em>) on fretting contact and wear behaviours of steel wires. Firstly, the fretting wear model for contact wires was established based on Archard’s wear model, and the accuracy of the model was compared with the published literature. Then, the fretting characteristics, such as wear morphology, relative slip amplitude (<em>δ_a</em>), and hysteresis loop, were investigated, and the action mechanism on wear depth was analysed. Finally, a more streamlined approach was proposed to predict wear depth by using dissipated friction energy. The results show that with an increase in the number of cycles, the relative slip amplitude gradually decreases, and non-Coulomb friction behaviour intensifies. The wear depth is influenced by the crossing angle and system stiffness mainly through the contact pressure and relative slip amplitude. Specifically, larger crossing angles and system stiffness result in more severe wear. An increase in contact load lead to a competition between contact pressure and relative slip, resulting in the initially increasing and then decreasing of wear depth. The effective dissipated friction energy, for the first time, was employed in wear prediction of steel wires. Compared to Archard's model, the prediction accuracy of the proposed model improves with the increasing system stiffness and the decreasing contact load. The proposed method offers a practical tool for wear prediction of steel wires, greatly enhancing the efficiency of wear calculations.</div></div>","PeriodicalId":50866,"journal":{"name":"Advances in Engineering Software","volume":"209 ","pages":"Article 103999"},"PeriodicalIF":5.7,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144723333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a new way of artificially generating point clouds by combining simulation and machine learning. Starting from the CAD model of the object to be virtually scanned and from a scan configuration, structured light simulation first allows reconstructing a preliminary 3D point cloud. Then, a coverage prediction network is used to predict the regions that would be acquired if a real acquisition was to be done. The prediction model has been trained from a large database of scan configurations and point clouds scanned for real. Finally, filtering and cropping are performed to fine-tune the generated point cloud. Experiments confirm that this method can generate point clouds very close to those that a real scanner would acquire, as shown by several metrics characterizing both local and global similarity. Such a virtual scanning technique enables the rapid generation of large quantities of realistic point clouds, especially when compared to the time-consuming and costly processes involved in using physical acquisition systems. This opens up new perspectives in terms of access to realistic point cloud databases, in particular for the development of various AI-based approaches.</div></div>","PeriodicalId":50866,"journal":{"name":"Advances in Engineering Software","volume":"209 ","pages":"Article 103996"},"PeriodicalIF":5.7,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144723369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequently, the representative values of temperature differences for the composite beam were calculated based on the analysis of historical meteorological data. The calculation method integrated the finite element temperature field model with the generalized extreme value distribution function. Finally, the simulated solar radiation temperature field was applied to the overall finite element model of the long-span bridge.

The results indicate that the finite element analysis results are in good agreement with the measured values. The 50-year return period representative value (<em>T</em>_d) for the maximum vertical positive temperature difference in the composite beam is 17.613 °C. The compressive stress induced in the concrete bridge deck of the composite beam by temperature loads during the operational phase exceeds twice that caused by lane loads. By analyzing seven different load effect combinations, the impact of the most unfavorable load effect combination on the bridge structure was determined.

We first establish a parametric optimization model based on equivalent magnetic circuit principles to characterize nonlinear thrust dynamics. To address limitations in conventional optimization approaches, we develop a differential evolution algorithm enhanced by a stochastic linear neural network (DE-SLNN). This hybrid method combines conventional linear neural networks (CLNN) with a stochastic dynamic opposite learning mechanism (SDOLM) to strengthen DE’s search capability. Comprehensive validation using CEC 2014 benchmark confirms DE-SLNN’s accelerated convergence speed and superior search performance. Application to reluctance actuator optimization demonstrates DE-SLNN’s ability to maintain full-stroke thrust output with a small deviation of less than 2.69% for stable gravity compensation, as confirmed by thrust distribution analysis. Comparative validation with finite element analysis (FEA) reveals thrust error control within 0.16%, verifying the optimization model’s precision.

This study employs advanced soft computing techniques, integrating FELA simulations, XGBoost, and optimization algorithms (PSO, GWO, and WOA), to predict the limiting uniform normal pressure behind circular and I-shaped contiguous piled walls in cohesive soil. The key factors in the prediction model include the soil properties, pile wall geometry, and soil strength parameters such as the spacing-to-width ratio (S/B or S/D), adhesion factor (m), height-to-width ratio of the I-section (H/B), and friction angle (<em>φ</em>).
