Deformation and collapse of the surrounding rock, leading to machine jamming, are critical factors hindering safe efficient operation Double Shield Tunnel Boring Machines (DS TBMs). Machine jamming can be categorized into shield cutterhead each influenced by various factors. Numerical simulation effectively quantifies impact these This paper examines calculation methods for thrust resistance torque in DS TBMs proposes a numerical method that accounts their tunneling process. A finite...
Abstract The effective implementation of the proportional integral derivative (PID) method is great significance for maintaining optimal control performance in practical industrial processes. However, inherent nonlinearity and complexity these processes pose significant challenges PID controllers. Especially, due to existence equipment errors environmental interference, sensors often suffer from measurement noise, which will have adverse effects on controller. In this article, a novel...
Abstract Strain engineering provides the ability to control ground states and associated phase transition in epitaxial films. However, systematic study of intrinsic character strain dependency transition‐metal nitrides remains challenging due difficulty fabricating stoichiometric high‐quality Here observation an electronic state highly crystalline antiferromagnetic CrN films with reduced dimensionality is reported. By shrinking film thickness a critical value ≈ 30 unit cells, profound...
Electronic states of a correlated material can be effectively modified by structural variations delivered from single-crystal substrate. In this letter, we show that the CrN films grown on MgO (001) substrates have orientation, whereas α-Al2O3 (0001) are oriented along (111) direction parallel to surface normal. Transport properties remarkably different depending crystallographic orientations. The critical thickness for metal-insulator transition (MIT) in 111 is significantly larger than 001...
Unlike land mining, the safety of seabed mining is seriously threatened by an overlying water body. In order to ensure subsea projects, it great importance understand failure characteristics and influencing factors strata deformation. Focusing on Sanshandao Gold Mine, a typical submarine deposit in China, geomechanical model testing numerical simulations were carried out. The results show that steeply dipping metal ore body, subsidence deformation mainly occurs hanging wall; center located...
An orthotropic steel deck (OSD) has a complicated structure, and its fatigue life is mainly determined by various welding details. Fatigue assessment of deck-to-rib details (DRWDs) under long-term train loads an important concern for engineers. Properly assessing the initial residual stress mechanism relaxation in DRWDs external loading prerequisite predicting damage service OSDs. In this paper, finite element analysis method proposed to calculate OSDs constant/variable amplitude cyclic...
In this paper, delay-independent stability of linear differential delay systems is considered. The continuous time model MIMO-NCS established. This close-loop essential a zero input time-invariant system with multi-delays. Based on the 2nd Lyapunov method, investigated and sufficient condition for to be uniformly asymptotically stable derived. conditions are form that readily computable conclusions obtained here have less conservative do not involve any assumption.
A novel multi-agent based on genetic algorithm (GA) is proposed to solve job-shop scheduling problem (JSSP). This not only can accelerate the creation of initial population and selection evaluation population, but also control processing selection, crossover mutation in an intelligent way. Job-shop benchmarks are used evaluate efficiency performance algorithm. The experimental result shows it has better optimal performance.
The overlying rock movement and mining pressure in the fully mechanized caving face with a large dip angle were systematically investigated according to theoretical analysis, similar material simulation, numerical calculation, field monitoring. following conclusions obtained: 1) analysis showed that roof characteristics at different positions of working are quite different. upper section is primarily controlled by structural instability main roof. stable structure easily formed middle lower...
Abstract Model-free adaptive control (MFAC) stands out as an effective data-driven method for addressing nonlinear problems in industrial processes. To maintain good performance, a set-point tuning (DDST) is used to update the virtual of MFAC system. The DDST-based (i.e. DDST-MFAC) constantly approaches target process through method. However, due equipment errors and external interference, sensors often suffer from measurement noise, which can have adverse effects on performance. In this...
For multi-grade chemical processes, current data-driven soft sensor models built in a specific operating condition cannot be directly applied to predict product qualities of other conditions. A simple transfer learning method namely domain adaptation extreme machine (DAELM) is presented construct model processes with limited labeled data. In addition, an effective strategy developed fast select the parameters. By exploring and utilizing useful information from different conditions,...
Abstract In this paper, modeling and control of networked system with different loop topology structures are considered.
