Design and Realization of 108MN Multi-function Testing System
With the rapid development of China economics, large buildings are beginning to appear. In order to ensure safety of the large buildings, 108MN Multi-Function Testing System (MFTS) built by HIT with 6-DOF and large loading force was proposed by China State Construction Engineering Corporation (CSCEC), which can research and evaluate the seismic performance of structures such as long columns building, cross shape joints, shear walls and 8 floors full scale building. This paper shows you the base function, system main structure parameter and performance characteristics of MFTS, detailed design process was given, inverse kinematics model based Hydraulic servosystem and compound control model of force and displacement were built to analysis the performance, simulation analysis results show that the MFTS can meet design requirements and the proposed controller has good abilities. The related experiments will be tested after MFTS is built.
