Abstract

The invention relates to a method for designing a receiving transducer of an electromagnetic ultrasonic surface wave, and aims to solve the problems that the conventional design of the receiving transducer of the electromagnetic ultrasonic surface wave is strong in noise receiving and complicated in processing. The method comprises the steps as follows: establishing the geometrical model of each element; setting material attributes; partitioning physical field solving areas; setting structural field parameters; setting electromagnetic field parameters; performing finite element subnetting and finite element solution; calculating induced voltage signals in receiver coils with different parameters; and completing the design of the receiving transducer of the electromagnetic ultrasonic surface wave eventually.

Description

technical field [0001] The invention relates to a design method of an electromagnetic ultrasonic surface wave receiving transducer. Background technique [0002] The electromagnetic ultrasonic surface wave receiving transducer generally adopts a meandering coil structure, mainly in the form of a printed circuit board and a skeleton. Among them, the skeleton form transducer is made of enameled wire winding, which is more efficient than the printed circuit board form transducer in receiving electromagnetic ultrasonic surface wave signals, and has been widely used in the field of electromagnetic ultrasonic applications. However, at present, the design of the electromagnetic ultrasonic surface wave receiving transducer in the form of skeleton is mainly based on experience. If you want to use enameled wires with a diameter of 0.19mm and a skeleton groove with a size of 1mm×1mm to design an electromagnetic ultrasonic surface wave receiving transducer, generally place 5 enameled w...
