| Abstract: | The principle of cable tension measurement based on magneto-elastic effect for steel cable is introduced.The magnetic circuit structure with double excitation and double circle is put forward.According to the theory of magnetic conductance,the magnetic circuit is theoretically analyzed,and the selection of magnetization mode and magnetic intensity is discussed in details.The structure design of the magnetic circuit was carried out.With the magnetization mode of pulse direct current and the magnetic intensity corresponding to the maximum permeability of the cable,experiments were processed.Experimental results indicate that the structure design of the magnetic circuit is reasonable and reliable.The repeat measurement accuracy is better than 0.5%. |
