Detection Sensitivity of Input Impedance to Local Defects in Long Cables

IEEE Access, 2020
Broadband impedance spectroscopy (BIS) has become a new method for detecting cable insulation defects, but the sensitivity of this method to local defects in cables has not been fully studied.

Study on prestress long-term loss of anchor cable considering coupled multiple factors

Rock and Soil Mechanics, 2021
In order to study the long-term loss law of anchorage force and the calculation method of prestress loss of anchorage force, a calculation method of the prestress loss of anchorage force was proposed to account for three factors.

Semiactive Control of Nonlinear Parametric Vibration of Super-Long Stay Cable in Cable-Stayed Bridge Installed with Magnetorheological Fluid Damper

Structural Control & Health Monitoring
As the stay cables of cable-stayed bridges become longer, parametric resonance with a large amplitude is more easily triggered, which becomes a vibration hazard of super-long stay cables.

Comparative analysis of frequency responses of options for constructing low-pass filters of electrical systems digital models

Известия Томского политехнического университета: Промышленная кибернетика
The use of digital twins in electric drive control tasks is driven by ever-increasing requirements for the quality of transient processes. The digital twin of a dynamic system is a discrete model, the use of which always entails some loss of accuracy and
