Electronic torsion fatigue testing machine customized for the standard of Nanjing Institute of Physical Education. Nanjing Institute of Physical Education is a provincial higher physical education institution that trains all kinds of applied sports talents for the society; it passed the undergraduate teaching level evaluation of the Ministry of Education in 2008 and was awarded the excellent grade. The first-level discipline of physical education was approved as'Jiangsu The first phase of the construction project of superior disciplines in universities and colleges is the subject of the project'.

The electronic torsion fatigue testing machine is mainly suitable for torsion testing of various materials such as automotive electromagnetic clutches, rubber recoil pulleys, metal and non-metal shaft products and connectors, and performs static or dynamic torsion fatigue durability tests, which can achieve torque and torsion Angle measurement and control. Increasing the corresponding environmental temperature test box can carry out torsion fatigue test of various parts environment simulation.

The technical indicators and parameters of the electronic torsion fatigue testing machine are as follows:

1) Maximum test torque: ±200 N.m;

　　 Test direction: forward and reverse test (same accuracy);

2) Clamping sample size: according to the user's sample to provide two kinds of test specifications fixture;

3) The distance between two chucks: 0—200mm continuously adjustable;

4) Display mode: torque and torsion angle are all digital display;

5) Control mode: It can realize closed-loop control of torque and torsion angle, and the two can be switched freely;
