Abstract: A new multifunction thermomechanical simulator was developed, by which about 20 functional tests may be fulfilled including tension, compression, torsion, combination of compression with torsion, combination of tension with torsion, etc. With the LabVIEW RT full development system applied to the newly-developed simulator for programming, the high-responsibility control and high-accuracy rapid measurements are available and prove not lower than those of domestic/foreign similar advanced systems. The designed functions, construction, man-machine interface, control system and main performance indices of the simulator are described.
