Experimental device and testing method for determining dynamic tensile tests of materials

Abstract

The invention discloses an experimental device and a testing method for determining dynamic tensile tests of materials. The device includes an incident bar and a transmission bar arranged oppositely. A first rod and a second rod with the same structure and opposite directions are arranged between the incident bar and the transmission bar. Both the first rod and the second rod are of U-shaped structure, the first rod is slidably connected with the second rod, the first rod is in contact with the incident bar, and the second rod is in contact with the transmission bar. A test piece is arranged between the first rod and the second rod, and two ends of the test piece are detachably connected with the first rod and the second rod respectively through connecting pieces. A monitoring assembly includes two sets of force sensors and two sets of strain gauges. The two force sensors are respectively arranged between the first rod, the second rod and the connecting pieces, and the two strain gauges are respectively arranged on the first rod and the second rod. The invention can realize the advantages of convenient component installation, simple test process and accurate data collection when determining the dynamic performance of materials.
