Connector life testing equipment, fatigue testing machine

　　Fatigue test refers to measuring 0-1 of metal material through metal material experiment, drawing S-N curve of material, then observing fatigue failure phenomenon and fracture characteristics, and then learning the method of measuring fatigue limit of metal material under symmetrical cycle, which is suitable for dynamic and static performance tests of various combined shock absorbers and tube shock absorbers. This series of products has the characteristics of wide output force range, high control precision, convenient use and high reliability. It can not only carry out dynamic high and low cycle fatigue tests and program-controlled fatigue tests, but also carry out static tests under the control of constant rate, constant strain and constant stress and various conventional mechanical properties tests, as well as fracture mechanics tests, and can also carry out fatigue life tests of materials or components in a broad range.
