振動制御用電磁石を用いた可撓性鋼板の磁気浮上システム Magnetic Levitation System of a Flexible Steel Plate with Vibration Suppressing Electromagnets
A magnetic levitation system is applied to the non-contacting conveyance of steel plate in a steel mill. In this system, the flexibility of the steel plate may deteriorate the levitation characteristic and so it is proposed to arrange the electromagnets along the steel plate length. A low pass filter is used to reduce the influence of the steel plate natural vibrations. Simulation results of the levitated plate's response by a finite element method and magnetic levitation experiments are presented. The results show the vibration suppressing electromagnet which only uses the velocity of the levitated object as a feedback is able to control the low frequency natural vibration effectively and a low pass filter is able to avoid the excitation of the high frequency natural vibration.
