Provided is a fixture applied to sticking a strain gauge on a Hopkinson square bar and a use method of the fixture. The invention is specially designed for a square waveguide bar, and the fixture further ensures consistency of the same group of strain gauges along a cross-section position of the bar. The fixture has important practical value in application in a dynamic true triaxial electromagnetic Hopkinson bar test, especially in a high-end material testing field requiring high-precision and high-reliability test data.

Fixture applied to sticking strain gauge on Hopkinson square bar and use method thereof

Provided is a dynamic true triaxial electromagnetic Hopkinson bar leveling and centering system and method. The system comprises a supporting base, a micrometer adjusting knob, a sliding platform, an auxiliary supporting plate, a fixing groove, at least two auxiliary centering targets and a lamp source. According to the auxiliary centering system, a principle that light rays are straight lines and two points form one line is adopted, and adjacent perpendicularity and coaxial centering leveling of a bar piece are determined by respectively adjusting a center of a loading end surface of the bar piece and an upper surface of the bar piece.
