Jinan lizhi Testing System Co., Ltd. has signed contracts with China Academy of Building Science, Liuzhou Overwem Machinery Co., LTD., National Engineering Laboratory of High-speed Railway Construction Technology, Central South University, China Academy of Railway Sciences, Liaoning Provincial Transportation Planning and Design Research Institute, and Tongji University for the development of heavy-load large-amplitude pulsating fatigue testing machine. The PMW1600-38 high pressure ultra-large pulsation displacement hydraulic station developed by the company is the world's leading technical index. The maximum pulsation displacement is 1600ml/ time, the maximum system working pressure is 38MPa, the maximum amplitude of the 1000kN actuator can reach 30mm, and the working frequency is 2-5Hz. The system meets the requirements of pseudo-static pseudo-dynamic performance test and fatigue life test of 1:1 full size test sample of 20,000-ton heavy-duty transport bridge of Shuohuang Railway under the National 863 Program. The successful implementation of this project has established Jinan Force Support Test System Co., Ltd. as the world leader in the field of electro-hydraulic pulsation fatigue test technology research and development.
