Summary

Modern urban planning and infrastructure become more complicated than traditional ones, and therefore present more requests. The requests of higher safety, accuracy, efficiency and environmental friendliness can be met with the assistance of computational mechanics. The 21st century witnessed high performance of computer methods in machine design and manufacturing. Civil engineers and researchers have also dedicated to achieving optimized designs with numerical simulation. The wide application of computational mechanics brings accompanying challenges such as error analysis and numerical stability. By sharing ideas and experiences among civil engineers and algorithm engineers, we hope to generalize robust solutions for existing problems and popularize computational mechanics in urban planning and infrastructure.

Ensemble Model for Spindle Thermal Displacement Prediction of Machine Tools
Ping-Huan Kuo, Ssu-Chi Chen, Chia-Ho Lee, Po-Chien Luan, Her-Terng Yau
CMES-Computer Modeling in Engineering & Sciences, Vol.137, No.1, pp. 319-343, 2023, DOI:10.32604/cmes.2023.026860

Abstract Numerous factors affect the increased temperature of a machine tool, including prolonged and high-intensity usage, tool-workpiece interaction, mechanical friction, and elevated ambient temperatures, among others. Consequently, spindle thermal displacement occurs, and machining precision suffers. To prevent the errors caused by the temperature rise of the Spindle from affecting the accuracy during the machining process, typically, the factory will warm up the machine before the manufacturing process. However, if there is no way to understand the tool spindle's thermal deformation, the machining quality will be greatly affected. In order to solve the above problem, this study aims to predict the thermal… More >

Interactive Trajectory Star Coordinates i-tStar and Its Extension i-tStar (3D)
Jing He, Haonan Chen, Lingxiao Li, Yebin Zou
CMES-Computer Modeling in Engineering & Sciences, Vol.135, No.1, pp. 211-237, 2023, DOI:10.32604/cmes.2022.020597

Abstract There are many sources of geographic big data, and most of them come from heterogeneous environments. The data sources obtained in this case contain attribute information of different spatial scales, different time scales and different complexity levels. It is worth noting that the emergence of new high-dimensional trajectory data types and the increasing number of details are becoming more difficult. In this case, visualizing high-dimensional spatiotemporal trajectory data is extremely challenging. Therefore, i-tStar and its extension i-tStar (3D) proposed, a trajectory behavior feature for moving objects that are integrated into a view with less effort to display and extract spatiotemporal… More >

Stability Analysis of Landfills Contained by Retaining Walls Using Continuous Stress Method
Yufang Zhang, Yingfa Lu, Yao Zhong, Jian Li, Dongze Liu
CMES-Computer Modeling in Engineering & Sciences, Vol.134, No.1, pp. 357-381, 2023, DOI:10.32604/cmes.2022.020874
（This article belongs to this Special Issue: Computational Mechanics Assisted Modern Urban Planning and Infrastructure)
Abstract An analytical method for determining the stresses and deformations of landfills contained by retaining walls is proposed in this paper. In the proposed method, the sliding resisting normal and tangential stresses of the retaining wall and the stress field of the sliding body are obtained considering the differential stress equilibrium equations, boundary conditions, and macroscopic forces and moments applied to the system, assuming continuous stresses at the interface between the sliding body and the retaining wall. The solutions to determine stresses and deformations of landfills contained by retaining walls are obtained using the Duncan-Chang and Hooke constitutive models. A case… More >

Dense-Structured Network Based Bearing Remaining Useful Life Prediction System
Ping-Huan Kuo, Ting-Chung Tseng, Po-Chien Luan, Her-Terng Yau
CMES-Computer Modeling in Engineering & Sciences, Vol.133, No.1, pp. 133-151, 2022, DOI: 10.32604/cmes.2022.020350

Abstract This work is focused on developing an effective method for bearing remaining useful life predictions. The method is useful in accurately predicting the remaining useful life of bearings so that machine damage, production outage, and human accidents caused by unexpected bearing failure can be prevented. This study uses the bearing dataset provided by FEMTO-ST Institute, Besançon, France. This study starts with the exploration of neural networks, based on which the biaxial vibration signals are modeled and analyzed. This paper introduces pre-processing of bearing vibration signals, neural network model training and adjustment of training data. The model is trained by optimizing… More >
