Description
技术领域technical field

背景技术Background technique
蠕变测试试验是指测定材料在一定时间周期的恒温和恒应力作用下，发生缓慢的塑形应变现象的一种材料机械性能试验。蠕变一般可在单一应力(拉力、压力或扭力)，也可在复合应力下发生。通常的蠕变试验是在单向压缩条件下进行的。目前，工业生产制造的过程中，为了更好的检验产品的材料性能，其中的检验手段之一就是蠕变试验。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.
由于蠕变试验的试验周期往往比较长(可达三至六个月)，现有的蠕变试验机主要存在的主要问题是一套设备往往只能对一组试件进行试验，进行多组实验时需要同时开启多套试验设备进行试验，极大的浪费了试验资源。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.
