Abstract

The invention discloses a stress and defect magnetic memory nondestructive testing virtual experiment teaching system and method, and the system comprises a VR all-in-one machine which is connected with a computer platform through a wireless network, and the computer platform is connected with a data glove through a positioning sensor. Based on the electromagnetic theory and a force-magnetic coupling mechanism, a virtual cutting testing machine, a tensile test virtual machine and a magnetic memory nondestructive testing virtual operation display system are developed and used for virtual experiment teaching of magnetic memory signals induced by complex defect morphology. Through the virtual diversified expression form, boring classroom teaching content is easier to be accepted by students,the teaching quality is improved, the content interestingness is enhanced, and the learning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of VR virtual development of nondestructive testing technology, in particular to a virtual experiment teaching system and method for magnetic memory nondestructive testing of stress and defects. Background technique [0002] The magnetic signal detection method is a new non-destructive testing method, which uses the distortion of the magnetic signal on the surface of the structure to detect and evaluate the position and size of the stress concentration area or defect. With the continuous development of non-destructive testing in my country, the experimental teaching of non-destructive testing such as magnetic memory methods has gradually entered the classroom, and the corresponding professional experimental equipment is indispensable in teaching and scientific research in colleges and universities. However, due to the high purchase cost of professional testing instruments, the large demand for students to pa...
