[0003] Through research and analysis, it is found that at present, most of the existing force-magnetic coupling test devices under stress conditions at home and abroad are force-magnetic coupling test devices that simulate simple load conditions, and such test devices can only apply relatively simple loads to tubular specimens
However, under actual working conditions, the force on an object is often a composite superposition of various loads, and the existing measuring devices cannot correctly summarize the change law of stress and magnetic field during force-magnetic coupling under this working condition.

Description
technical field [0001] The present application relates to the technical field of stress and magnetic field detection, and in particular, to a pipeline magnetization simulation detection system under the action of composite loads. Background technique [0002] At present, with the advancement of science and technology and the in-depth study of electromagnetic theory, the law of force-magnetic coupling detection of stress and magnetic field in the fields of construction, civil engineering, pipeline oil and gas transportation, aerospace and other fields has attracted great attention. [0003] Through investigation and analysis, it is found that at present, the existing force-magnetic coupling test devices under stress conditions at home and abroad are mostly force-magnetic coupling test devices under simple load conditions. Such test devices can only apply relatively simple loads to tubular specimens. . However, under the actual working conditions, the force on the object is o...
