“…Ref. [34] noted that "modern dynamic torque sensor operating principles are based mainly on strain gauges [35], acoustic interference [36,37], the effects of magnetic permeability and resistance [38,39], and optical polarization [39,40]". It was noted that "existing technologies fail to satisfactorily solve the problem of connecting to a rotating sensing element, especially for transient conditions".…”

This article outlines the relevance of building online telemetry systems for online monitoring of the technical conditions of rolling mill equipment. Electromechanical systems of the horizontal stand of the plate Mill 5000 are described, when operating in harsh conditions caused by the shock loading when workpieces enter the stand. It is noted that dynamic torque overloads, exceeding the rated motor torque by many-fold, cause the fatigue failure of spindle joints and breakage of rolls. In this regard, the development and implementation of systems for monitoring the elastic torque on spindles are extremely urgent. This issue has long been studied, but the references provide no information on the building principles and hardware composition of such systems. The use of strain gauges connected according to a balanced bridge circuit to measure the elastic torque is justified. This paper’s contribution is the proposed modular principle for building a telemetry monitoring system based on the analysis of known techniques for measuring and transmitting diagnostic data. The developed system structure is provided and the concept of data transfer and processing are explained. This article suggests the inductive power supply of a measuring unit mounted on a shaft without the use of batteries. A hardware structure was developed to be applied in a system for measuring, transmitting, and visualizing signals proportional to the elastic torque, manufactured on the basis of data measuring instruments by leading companies. The specifics of placement and connection of strain gauges are considered. The hardware providing a wireless power supply to the signal encoder and digital data transfer between the transmitter and receiver is described. The results of implementing the system on Mill 5000 are provided. The installation of a telemetry ring and a receiving head for the inductive power supply and data reception is shown. An experimental assessment of the elastic torques occurring when workpieces enter the cage was obtained by implementing a drive control algorithm which provided biting in the drive acceleration mode. The reliability of measuring the elastic torque with an error not exceeding ±5% and the reduction of dynamic loads on the spindle by 1.3–1.5 times due to the elimination of impacts from closing angular gaps in spindle joints was confirmed. This increases the service life of mechanical equipment and reduces the cost of eliminating the accident aftermath. The prospect of modifying the developed system into a cyber-physical system for monitoring the rolling mill’s mechatronic equipment conditions is shown.

“…However, current technologies face challenges in extracting torque information from the rotating shaft without interfering with the process. [44][45][46] While there have been several improvements and advances in developing new torque sensors, 47 the needs for self-power supply, ease of signal transmission, and high sensitivity are still urgently required. Here, a novel physical mechanism based on the two-point magnetic plucking system is developed for torque sensing.…”

A self-powered SECE (synchronized electric charge extraction)-based energy sensor is developed and applied to measuring shaft torque. The design is based on the setup of two-point magnetic plucking allowing the torqueinduced phase angles between two pairs of magnets. The result shows the realization of broadband energy harvesting due to inducing mixed resonant modes of vibration from frequency up-conversion and enhancement by SECE. In addition, torque sensing is achieved by measuring the variation of modal amplitude of voltage response against the phase shift angles. For the case of torque sensing operated at the second resonant mode, the phase angle against the voltage is multi-valued. A solution for the unique sensing is to develop a CNN (convolution neural network) classifier capable of distinguishing various voltage waveforms from different phase angles. The prediction agrees reasonably with experiment.

“…The state of theoretical studies of MAEs is discussed at length in [ 7 , 11 , 23 , 24 ]. The interest surrounding MAEs is driven by their potential applications in civil engineering as vibration dampers, remotely controlled switches, and noise control systems [ 25 , 26 , 27 , 28 , 29 , 30 , 31 ], in soft robotics as actuators [ 13 , 14 , 32 , 33 , 34 ], in entertainment as parts of haptic feedback devices [ 15 , 35 , 36 , 37 ], in biomedical devices as adaptive compressors and seals [ 38 , 39 , 40 , 41 , 42 ], in communication systems as microwave and radio frequency filters [ 43 , 44 , 45 ], and in automobile production as active braking systems [ 46 , 47 , 48 ]. Historically, the majority of both fundamental and applied research concerning MAEs has centered on harnessing the bulk properties of these materials.…”

A finite-element model of the mechanical response of a magnetoactive elastomer (MAE) volume element is presented. Unit cells containing a single ferromagnetic inclusion with geometric and magnetic anisotropy are considered. The equilibrium state of the cell is calculated using the finite-element method and cell energy minimization. The response of the cell to three different excitation modes is studied: inclusion rotation, inclusion translation, and uniaxial cell stress. The influence of the magnetic properties of the filler particles on the equilibrium state of the MAE cell is considered. The dependence of the mechanical response of the cell on the filler concentration and inclusion anisometry is calculated and analyzed. Optimal filler shapes for maximizing the magnetic response of the MAE are discussed.
