Abstract
The present invention discloses a double cantilever beam-encoding lead screw combined sensing tensile test method and machine. The double cantilever beam-encoding lead screw combined sensing tensile test machine comprises a main frame, a standard, a test piece and a microcomputer numerical control unit. The main frame is a force-deformation combined sensing mechanism composed of a double cantilever beam sensor, an encoding lead screw and a drive device. The double cantilever beam sensor is composed of a fixed cantilever beam sensor and a movable cantilever beam sensor. The encoding lead screw is composed of a drive lead screw and a tristate encoder. The double cantilever beam sensor matches with the encoding lead screw to achieve three functions, namely, test piece clamping, force sensing and deformation sensing, as well as to measure the size of the test piece.
