Abstract
Provided are an energy absorbing and buffering device applied to a dynamic true triaxial electromagnetic Hopkinson bar and a testing and using method thereof. The device comprises an energy absorbing and buffering ring, an exhaust pipe and an inert gas storage bin. According to the testing and using method, the energy absorbing and buffering device is utilized and connected with a waveguide bar through a middle hollow structure; and a rear end of the energy absorbing and buffering ring is tightly attached to a baffle at a confining pressure loading end. The energy absorbing and buffering device provides energy absorbing and buffering for the waveguide bar, which prolongs a service life of the waveguide bar under an impact load.
