Electro-hydraulic servo torsion fatigue testing machine

Function summary:

      Electro-hydraulic servo torsion fatigue testing machine is mainly to do reciprocating torsion fatigue test of shaft samples, the test object can be metal, non-metal, composite materials and other material samples, it can also be the structural parts of the shaft, such as automobile drive shaft and so on。The test environment can be room temperature, high temperature, low temperature, salt spray and other environments (need additional environmental tank)。

      

Relevant standards:

1) GB/T 2611-2007 "General Technical Requirements for Testing Machine"

2) GB/T 12443-2007 "Torsional Stress fatigue test Method for Metal Materials"
