The working principle and technical requirements of stainless steel metal torsion tube were discussed. According to the life test requirements of stainless steel metal torsion tube, a set of measurement and control system based on hydraulic actuating cylinder was designed, by which the working state of the torsion tube could be effectively simulated, and the main parameters such as angle, pressure and temperature could be monitored and recorded in real time during the test. The test results show that the parameters of the life test of the torsion tube meet the design requirements.
