Problems solved by technology
The labor intensity is high, and the volatile gas of energetic materials will endanger the physical health of workers. When workers are tired, manual shearing will often produce waste products.
Technology upgrading is particularly important. It is necessary to design shearing equipment for energetic materials instead of manual cutting. However, for the shearing process of energetic materials, there are no clear values for parameters such as shearing speed, shearing blade, and shearing force for reference.

Description
technical field [0001] The invention belongs to the field of energetic material shear testing, in particular to a testing device and testing method for energetic material shear process speed and blade. Background technique [0002] With the improvement of social production level, the upgrading of production technology in the field of industrial production is inevitable. At present, in the process of shearing energetic materials, workers hold a cutter to complete the material cutting work. The labor intensity is high, and the volatile gas of energetic materials will endanger the physical health of workers. When workers are tired, manual shearing will often produce waste products. Technology upgrading is particularly important. It is necessary to design shearing equipment for energetic materials instead of manual cutting. However, for the shearing process of energetic materials, there are no clear values for parameters such as shearing speed, shearing blade, and shearing fo...
