Optimization Design of Electromagnetic Ultrasonic Transducer
In order to improve the energy transduction efficiency of electromagnetic ultrasonic transducer (EMAT), a 2-D simulation model for the electromagnetic ultrasonic transducer is established and optimized. Aiming at the main object in EMAT optimization, the analysis of the impact that the coil and the lift-off distance of the tested pieces, incentive coil and various parameters of the permanent magnet have on the energy transduction efficiency is conducted. Ultimately, the optimum combination of the incentive coil parameters is determined.
