Material mechanical performance testing platform for small-sized test sample under stretching bending composite loading mode

The invention relates to a material mechanical performance testing platform for a small-sized test sample under a stretching bending composite loading mode and belongs to the field of material mechanical performance test. The material mechanical performance testing platform consists of four parts, namely a driving module, a stretching module, a bending module and a control detection module and can be used for carrying out uniaxial stretching test on the test sample or material mechanical performance test on the test sample under the stretching bending composite loading mode. The motion between the stretching module and the bending module is connected through an electromagnetic clutch; and during test, the loading time sequence of the bending module relative to the stretching module is controlled by controlling the power on/off of the electromagnetic clutch and further pull combined loads with different ratios are acquired indirectly. The material mechanical performance testing platform disclosed by the invention is novel in concept and compact in integral structure. For researching the mechanical performance of the test sample under the action of a random composite load for stretch bending, the invention provides an effective research means and strong practicability is obtained.
