This paper describes of rigidflexible coupling experiment table based on the virtual instrument technology. A series of physical measurement angle, angular velocity, and strain is realized based on CompactDAQ and digital I/O modules. It used to validate a variety of rigidflexible coupling models. the rotation of the table electromagnetic gascan validate effect of different control methods rigidflexible coupling system. his experiment table has characteristics low cost, high precision, high reliability and flexible extension.
