1. A dynamic true triaxial electromagnetic Hopkinson bar system, comprising a central cubic box, wherein
confining-pressure loading systems, electromagnetic pulse generators, square bars, circular bulges, and self-lubricating square bar fixation and support frames in directions X+, X−, Y+, Y−, Z+, and Z− are respectively symmetrically arranged by taking the central cubic box as a symmetric center;
the central cubic box completely opens in the direction Z+;
a square opening is disposed at a center of the central cubic box in each direction of X+, X−, Y+, Y−, and Z−, respectively;
a size of the square openings is the same as that of the square bar;
the central cubic box is disposed on a center of an upper surface of a central support platform;
the central cubic box and a horizontal cruciform support platform form an orthogonal coordinate system, wherein the horizontal cruciform support platform comprises the central support platform and support platforms in the directions of X+, X−, Y+, and Y−; and
the six systems in the directions X+, X−, Y+, Y−, Z+, and Z− together construct the dynamic true triaxial electromagnetic Hopkinson bar system.
