Real-time monitoring of wire rope tension is of great significance to the safe operation of mine hoist.Due to the longitudinal and lateral coupling vibration of wire ropes during the operation of hoist, there are high frequency components in measured tension signals of click here wire ropes, which cannot effectively characterize the actual lifting load.To overcome this problem, a particle damping sensor with a vibration dissipation function is designed in this paper.Multilayered steel balls are placed into the cylindrical cavity of the sensor.

Damping vibration and energy dissipation will occur when the sensor is subjected to external excitation.Then, to obtain the optimal sensor characteristics, relevant parameters of the particles and the spoke structure are simulated.Finally, the sensor based on the optimized royal nomadic 5413 rug parameters is manufactured and tested in a coal mine.Compared with the general pressure sensor, the particle damping sensor can effectively eliminate the influence of wire ropes vibration on tension measurement and achieve accurate measurement results.
