Stick-slip stabilization in oil well drill-strings via optimal hybrid fractional order fuzzy logic control scheme

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2023
Stick-slip vibration is regarded as one of the major factors that negatively influence the efficiency of the drilling processes. Therefore, it would be highly preferable to overcome the stick-slip vibration challenge through an effective control scheme ...

Optimum design of SRC composite beams [PDF]

open access: yesInternational Journal for Simulation and Multidisciplinary Design Optimization, 2008
Based on experimental study of bond-slip behaviours between steel shape and concrete, an optimal design scheme of single objective and discrete variables is proposed to design steel reinforced concrete (SRC) frame beams.

Study on the fault slip rule and the rockburst mechanism induced by mining the panel through fault

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources, 2023
Abstract When mining operations are conducted near faults can cause the fault to slip and release energy, resulting in a rock burst and posing a significant safety risk to coal mine production. This paper proposes a numerical simulation method, based on FLAC3D numerical simulation, for calculating the dynamic forces of fault slippage below the ...

A Predictive Energy Management Strategy for Multi-Energy Source Vehicles Based on Full-Factor Trip Information

open access: yesSensors, 2021
To achieve the real-time application of a dynamic programming (DP) control strategy, we propose a predictive energy management strategy (PEMS) based on full-factor trip information, including vehicle speed, slip ratio and slope.
