hysteresis nonlinearity and frequency doubling phenomenon of giant magnetostrictive(GM) materials
it is proposed that driving signal of giant magnetostrictive transduer should have the ability of reducing domain inertia
weakening remanent magnetization and eliminating frequency doubling phenomenon
combined with the above factors
a new driving signal which can meet the requirements is established.Experimental results show that driving efficiency of the proposed transducer is prior to that of the square wave and trapezoidal wave signals.The proposed viewpoint lays a foundation for drive circuit design of transducer.
