MTS809材料试验系统改造与扩展
The Transformation and Expansion of the Material Testing System 809
摘要
Abstract
Material testing system based on the Electro-Hydraulic servo technology consists of four main subsystems： machinery-power subsystem, sensing-servo subsystem, acquisition-control subsystem, the temperature-environment subsystem. Advanced materials testing system has a very short update cycle, it mainly reflects in the upgrading of the control system. MTS809 is a typical pull and torsion material testing system, which uses an outdated analog control technology, and the control part has not worked The realization of the test system functions depends mainly on the control system and hydraulic chucks and accessories. But the old MTS809 was not equipped with a universal multifunctional chuck. For these two issues, we designed and carried out the renovation and expansion of the MTS809, including the configuration of the digital control system, multi-function hydraulic chuck, and the straight-line actuator. Practice showed that： the new digital control system has a high control precision, easy to operate; INSTRON hydraulic chuck is fully functional; Straight line actuator can do some structural test to expand the MTS809＇s functions.关键词
