Multi-dimensional electromagnetic-driven hopkinson test device

Abstract

The invention discloses a multi-dimensional electromagnetic-driven Hopkinson test device, which comprises a main frame, wherein the main frame consists of two supporting plates arranged in a cross shape; a transmitter and an incident rod are sequentially installed at the top of one end of the supporting plate; a transmission rod is arranged at the top of the other end of the supporting plate; a plurality of supporting mechanisms are arranged on the supporting plate; the incident rod and the transmission rod are both connected with the supporting plate through the supporting mechanisms; and a test block is arranged between the incident rod and the transmission rod. In the experiment of a multi-dimensional electromagnetic-driven Hopkinson test device, the bullet is accelerated by the transmitter, so that the bullet collides with the incident rod, and both the incident rod and the transmission tube are provided with strain gauges, and after the impact, incident waves, reflected waves and transmitted waves are collected by the strain gauges stuck on the incident rod and the transmission rod.
