Problems solved by technology

The main function of the device is to measure the anti-destructive strength of the test plate under the action of transient high-speed impact, which can effectively judge whether the test plate is qualified or not, and conduct performance strengthening tests after the test plate is qualified. Patent No. ZL200410021245.9 provides a double The pendulum testing machine and the test method just tilt the test plate at a certain angle to the direction of the falling weight. However, although this test method can obtain the energy value absorbed by the test plate in the horizontal and vertical directions, it cannot The real-time instantaneous energy change of the material is displayed

Abstract

The invention discloses a double-swing-rod impact testing machine. An upper swing rod and a lower swing rod are designed to realize the free states of the upper and lower swing rods when a test plate is impacted by the swing hammer of the lower swing rod in order to realize the bidirectional impact and detection of the test plate. When the double-swing-rod impact testing machine is normally used, a connection apparatus is used to well fix the upper and lower swing rods, so the upper and lower swing rods are in a free state when the test plate is impacted by the lower swing rod to realize normal use.

Description

technical field [0001] The invention relates to a double pendulum impact testing machine, in particular to a machine capable of bidirectionally measuring the surface of a test plate [0002] Double pendulum impact testing machine for damage resistance under transient impact. Background technique [0003] The double pendulum impact testing machine is a new equipment specially developed for the bidirectional performance test of the surface of the test plate under the instantaneous load. The main function of the device is to measure the anti-destructive strength of the test plate under the action of transient high-speed impact, which can effectively judge whether the test plate is qualified or not, and conduct performance strengthening tests after the test plate is qualified. Patent No. ZL200410021245.9 provides a double The pendulum testing machine and the test method just tilt the test plate at a certain angle to the direction of the falling weight. However, although this te...
