Test instrument of shock resistance of high performance material

Abstract

The invention provides a test instrument of shock resistance of a high performance material, comprising a heavy hammer and a heavy hammer lifting device, wherein, the heavy hammer lifting device comprises a power structure, a shifting rod and a rocker arm; the shifting rod is connected on the power structure and can be rotated by the power structure; the rocker arm is arranged on a rotating shaft; when a first end of the rocker arm is opposite and parallel to the outer end of the shifting rod, the rocker arm and the shifting rod are in staggered and contact state, the first end of the rocker arm is positioned at the lower part of the shifting rod, and a second end of the rocker arm is connected with the heavy hammer by a lifting rope. The test instrument also comprises a limiting part for limiting the rotating range of the rocker arm. The test instrument of shock resistance of the high performance material has simple structure and convenient operation and can automatically complete continuous shock test.

Description

technical field [0001] The invention relates to an instrument for testing the impact resistance of high-performance materials. Background technique [0002] When testing the impact strength of high-performance materials such as epoxy resin mortar materials, engineering plastics, and glass fiber reinforced plastics, impact resistance testing instruments are required. Most of these testing instruments use the impact force generated when the weight falls freely for testing. One of them is a test instrument with a simple structure. It is necessary to use the lifting device to lift the weight first and then lower the weight to complete an impact. For example, use the power structure to pull or roll up the steel wire rope. , the heavy hammer completes the free fall, and then starts the power again, so the reciprocating motion. However, this kind of device requires additional control of the intermittent movement of the power structure, or manual control of the connection and disc...

AI Technical Summary

Problems solved by technology

However, this kind of device needs to additionally control the intermittent movement of the power structure, or manually control the connection and disengagement of the lifting device and the power structure, which cannot complete the continuous test, and the operation is cumbersome

The other is an automated test instrument, whose test principle is similar to the working principle of the above-mentioned simple-structure test instrument, but is equipped with an automatic control system. Although this automated test instrument makes up for the shortcomings of the above-mentioned simple test instrument, but The structure is more complex and the cost is higher
