Abstract

The invention relates to a novel material testing machine, which consists of four parts, namely, a control system, a detection system, a tension, compression and torsion system and a bending system. In the control system, an industrial personal computer controls a motion control card through a software system, so that the motion control card drives a stepper motor to rotate by a shaft coupling and then drive a first worm, a second worm and a lifting platform to move to realize motion control. The detection system consists of an STSS-1 stress-strain module and a loading sensor. The tension, compression and torsion system consists of a shaft, a movable base and a pair of round four-jaw chucks, wherein the two ends of the shaft are provided with threads of which screwing directions are opposite; the movable base is in threaded connection with the shaft; and the pair of round four-jaw chucks is fixed on the movable base. The bending system is used for clamping the lifting platform which can move up and down on the upper surface of the middle part of a fixed base; and a loading head is arranged on the lifting platform. The novel material testing machine realizes tests in the two-way stretch, compression and torsion of work pieces, and can realize various combined two-way or one-way tests.

Description

technical field [0001] The invention relates to a material testing machine capable of conducting combined experiments. In particular, it relates to a material testing machine with simple structure, complete functions and capable of bidirectional loading and compound loading. Background technique [0002] With the rapid development of industrial technology, the measurement of various mechanical properties of materials, such as the measurement of tensile, compression, torsion and bending properties, has been widely used in many fields from scientific research to teaching, military to industry, industry to civil, etc. However, the existing material testing machine has two extremes due to its own design, structural size, etc., which limit its application range. One is the testing equipment that can only realize a single test method, but cannot satisfy some combined tests. The other is a multifunctional material testing machine, which has a huge mechanism, complex structure, and...
