Disclosed is a synchronous and dynamic loading method in electro-magneto-thermo-mechanical multi-field coupling conditions. The method comprises the following steps: applying maximum pulse current to a test object by a pulse power supply to realize loading in extreme electric field and magnetic field conditions; meanwhile, generating a large amount of friction heat by the high-speed rotation of a rotating body and the friction of the test object to realize loading in an extreme-temperature field combined with a large amount of Joule heat and arc heat; synchronously applying pressure to the rotating body by a pressure device to realize loading of extreme force combined with the gravity of the rotating body and the friction force between the rotating body and the test object.

Synchronous and dynamic loading method in electro-magneto-thermo-mechanical multi-field coupling conditions

Disclosed is an electro-magneto-thermo-mechanical dynamic and synchronous loading device based on a wedge-shaped rotating body. The device comprises a carrier, a wedge-shaped rotating body and a pulse power supply, wherein the wedge-shaped rotating body is positioned above the carrier, the pulse power supply is connected to the carrier and the wedge-shaped rotating body through conductors, a test object is fixed on the carrier, the top of the wedge-shaped rotating body is connected to the output end of a driving shaft through a transmission shaft, the driving shaft drives the wedge-shaped rotating body to rotate and can apply downward pressure, and the wedge-shaped rotating body can be pressed against the test object and rotate on the surface of the test object.
