A new substructure on-line test system combining with general-purpose finite element software is proposed in this paper. In this system, some substructures are analyzed numerically by a general purpose finite element software called ABAQUS, while the others are tested by physical experiment. A control program in charge of the numerical analyses and physical experiments is developed to generate a series of input files for ABAQUS, obtain results from ABAQUS analysis and solve the equations of motion. ABAQUS provides restart analysis capability to be used repeatedly to get the reaction forces of the analyzed substructures. ABAQUS is implemented by this system like a 'black box' with displacements as input and reaction forces as output. The entire operation goes smoothly without malfunction, and the obtained responses are very reasonable. It demonstrates that the substructure on-line test can be conducted in combination of a commercial finite element program but without touching upon the inside of the program.
