Abstract

The invention discloses a loading device and a debugging method for an epoxy resin model fracture test, and belongs to the technical field of experimental mechanics. The loading device is composed of an electric control system, a detection sensing system, system software and a mechanical tool, wherein the electric control system comprises a PLC, an upper computer, a frequency conversion speed regulator and a motor, the mechanical tool comprises a base used for supporting and fixing the motor, a plum blossom joint elastic coupling installed on an output shaft of the motor, a transmission shaft, a stand column type bearing seat and an incubator inner bearing seat. The real working condition of the prototype is simulated when the epoxy resin model fracture test is carried out, the elastic-plastic state of the prototype is simulated by utilizing the transition state of the model, and the test precision is improved. The circumferential pre-tightening force is added to the epoxy resin model, so that the deformation of the model before fracture is reduced, and the test is more in line with the real working conditions of the prototype.

Description

technical field [0001] The invention belongs to the technical field of experimental mechanics, in particular to a loading device and a debugging method for an epoxy resin model rupture test. Background technique [0002] The epoxy resin model is widely used in the field of experimental mechanics, and it has good optical and mechanical properties. Its test device is generally relatively simple, suitable for applying tension, compression, bending, torsion, centrifugal and other loads. The current model hybrid loading device and the photosensitive resin model centrifugal loading device are both designed for elastic stress analysis. The model used in the test works in a highly elastic state, and the material is completely elastic. The directly obtained model stress is converted into the prototype stress through similarity theory. , this technology cannot effectively obtain the fracture speed and fracture position at present. At present, the test technology for obtaining the ru...
