Magnetic Displacement Sensor is a high-precision, long-stroke absolute position measurement displacement transducer manufactured by the principle of magnetic striction. It can not only measure the linear displacement of moving objects, but also give the position and speed analog signals or liquid leve...
The systematic structural design of a giant magnetostrictive transducer based on the circuit theory and system dynamic equation has been proposed. The equivalent circuit of the transducer's vibrational components has been established and the frequency equations of resonance state and educing the dimensions...
Fig. 1b demonstrated the working principle of the giant magnetostrictive actuator. The lower end of the giant magnetostrictive rod was fixed to the still block and the upper end pressed on the cap which was in threaded connection to the output rod. With the coil electrified, the unbiased ...
Giant magnetostrictive actuator (GMA) is a transducer which uses the characteristics of GMM producing deformation under the action of external magnetic field to realize the conversion from electromagnetic energy to mechanical energy. Currently, GMA has been applied in many areas, such as high power ...
