Aiming at the electromagnetic optimization method of 32kN electric shaker,the simplified model and cir-cuit model of the shaker are established,and the electromagnetic optimization of the electric shaker is studied and tested based on finite element method.The results show that the method is effective,and the electromagnetic force of the shaker increases by 41.24%,19.33%and 19.54%respectively in low,middle and high frequency bands after the optimization of the magnetic circuit.
