High-flux small sample tension, compression and bending test system and method

The invention relates to a high-flux small sample tension, compression and bending test system. The system comprises a computer unit, a motor and a plurality of sample testing modules which are horizontally or vertically arranged on a workbench, the sample testing module comprises a sample testing module bottom plate fixedly connected to the workbench, and a ball screw, a displacement sensor, a moving cross beam, a clamp unit, a linear moving platform unit and a force value sensor which are arranged on the sample testing module bottom plate; the plurality of sample testing modules are arrangedin parallel on the workbench or are circumferentially and uniformly distributed by taking one point on the workbench as a circle center; the motor drives the ball screws of the sample testing modulesto rotate synchronously through the transmission device, synchronous back-and-forth movement of the movable cross beams of the sample testing modules is achieved, and then synchronous stretching, compressing, bending and othe
