A Simultaneous Multi-Stage Loading Creep Testing Machine

Abstract

The object of the present invention is to provide a simultaneous multi-stage loading creep testing machine, including a control device, a power device, a transmission device, a loading device, a measuring device, a data acquisition device and a test stand. When the simultaneous multi-stage loading creep testing machine is working, it first controls the power device to work through the control device, and drives the loading device through the transmission device to complete the loading of the load required for the test. During the test, it is measured by the measuring device under the corresponding load. The displacement of the test piece and the deformation displacement of the tested piece during the whole test are transmitted from the measuring device to the data acquisition device. According to the test requirements, the present invention can realize a set of simultaneous multi-stage loading creep test machine to perform creep test tests with different loads at the same time, thereby improving test efficiency and saving test cost and time.

Description

technical field [0001] The invention relates to a simultaneous multi-stage loading creep testing machine which maintains the load under a certain load so as to detect the deformation amount of the test piece in the compression direction. Background technique [0002] Creep test refers to a kind of material mechanical performance test that determines the slow plastic strain phenomenon of materials under constant temperature and constant stress for a certain period of time. Creep can generally occur under single stress (tension, compression or torsion) or under compound stress. Usually creep tests are carried out under unidirectional compression conditions. At present, in the process of industrial production and manufacturing, in order to better test the material properties of products, one of the testing methods is creep test. [0003] Since the test period of the creep test is often relatively long (up to three to six months), the main problem of the existing creep testing...

AI Technical Summary

Problems solved by technology

[0003] Since the test period of the creep test is often relatively long (up to three to six months), the main problem of the existing creep testing machine is that a set of equipment can only test one group of specimens, and multiple groups During the experiment, multiple sets of test equipment need to be turned on at the same time for testing, which greatly wastes test resources
