Developed a batch of 100KN electro-hydraulic servo dynamic fatigue testing machine and 20000N.m microcomputer controlled torsion testing machine for Wuhan University of Technology. Wuhan University of Technology is a national key university jointly established by the Ministry of Education, the Ministry of Transport, and the National Defense Science, Technology and Industry Administration. It is the first batch of national key universities for the 211 project and the 985 project superior discipline innovation platform.

Electro-hydraulic servo fatigue testing machine is mainly used to test the dynamic and static mechanical properties of various metals, non-metallic materials, composite materials, aerospace, automobiles and parts. It can perform tensile, compression, bending, low-cycle and high-cycle fatigue tests under sine wave, triangle wave, square wave, trapezoidal wave, random wave, and combined waveform.
