Abstract: Abstract:Multi-rope friction hoister exists the problems of imbalance wire rope tension and the ascending overload.The wire rope tension measured by the general sensor exists severe fluctuations and can not represent the actual tension and load effectively.A kind of particle damping vibration attenuation sensor is designed,which is loaded with steel beads in the cavity structure. When the sensor is pushed by the piston rod,the particle damping vibration is induced by the collision and friction between the steel balls and between the steel ball and the container wall. The impact load caused by the coupling vibration of the wire rope can be dissipated effectively and the noise in the tension signal of the wire rope can be filtered out.by the particle damping vibration.Compared with universal pressure sensor, this sensor can monitor the tension and lifting load of wire rope more accurately and effectively.
