Abstract

The invention discloses a soft film fatigue testing machine device, which comprises a clamping module, a loading module, a transmission module and a monitoring module. Wherein, the clamping module is used to clamp the peripheral portion of the soft film; the loading module is located on one side of the flexible film clamped by the clamping module; the transmission module is connected to the loading module , to drive the loading module to apply a periodic out-of-plane load to the soft film on the clamping module, so that the soft film does periodic reciprocating vibration along the normal direction of the soft film; the monitoring The module is used to monitor one or more of the out-of-plane load state, deformation state and fatigue state of the soft film. The invention can carry out the fatigue test on the soft material film bearing reciprocating out-of-plane load, and has the advantages of small size, simple structure, independent modules, flexible assembly and disassembly, low cost, and convenient popularization and application.

Description

technical field [0001] The invention relates to the technical field of soft film fatigue testing, in particular to a soft film fatigue testing machine device. Background technique [0002] In people's production and life, many materials such as workpieces and even structures are subjected to alternating loads, such as gears and rolling bearings. These materials often fail under cyclic loading well below the material strength limit. Due to the gradual change and concealment of fatigue failure of materials, it poses a great threat to people's production and life safety. With the maturity of industrial technology and the development of scientific research, people have developed some methods of suppressing material fatigue, shot peening process; for common workpieces, some fatigue test data have been accumulated. However, the aforementioned advances in fatigue have mainly been for hard materials. [0003] With the development of material technology and bionic science, soft ma...
