A finite element analysis and a parametric optimization of single-axis acoustic levitators are presented. The finite element method is used to simulate a levitator consisting of a Langevin ultrasonic transducer with a plane radiating surface and a plane reflector. The transducer electrical impedance, the transducer face displacement, and the acoustic radiation potential that acts on small spheres...
Finite element model of a electromagnet module was established on the dimensions of long stator linear synchronous in TR08 Maglev vehicle in order to study the performance of the motor. The distribution of the electromagnetic field in the levitation air gap was analyzed in detail, then the curve of propulsive force and levitation force were obtained under different spans. The force variation trend...
