Description

technical field [0001] The invention relates to the technical field of tensile loading test, in particular to a different-direction synchronous load test device and its use method. Background technique [0002] combine Figure 8 The structure of a locking mechanism is shown, and its functional principle is to drive the guide rail through the output screw of the driving mechanism to realize the locking of the X-direction force-bearing ring and the locking of the Y-direction force-bearing pin. Design index requirements: synchronous loading is carried out through the passive end installation interface of this locking mechanism, and the loading capacity requirement is X direction: (4±0.2) kN, Y direction: (21±0.2) kN. [0003] Existing test equipment can only complete the one-way tension and compression load test, or complete the synchronous load test in different directions by hanging weights in the other direction. Although the method of hanging the weight is in the horizonta...
