Abstract
Description
Technical Field
[0001] The invention belongs to the field of cutting and processing, and in particular relates to a cutting and processing device for solid propellant or other energetic materials used for multi-axis mechanical test. Background Art
[0002] The storage life of solid motors mainly depends on the propellant grain, which is mainly made of solid propellant poured and solidified. The material properties of solid propellants are relatively complex and are easily affected by changes in temperature, strain, and pressure. During long storage, they will experience temperature differences and surface corrosion, causing the propellant to expand and contract repeatedly, resulting in cracks, embrittlement, sweating, crystallization, etc., and the mechanical properties will decrease rapidly. Therefore, studying the damage behavior of solid propellants is of great significance for guiding formulation design, grain structure design, and ensuring the normal operation of solid motors.
[0003] Due to the strong oxidant (ammonium perchlorate) inside the HTPB solid propellant, its physical and chemical properties are extremely unstable, and its mechanical sensitivity and thermal sensitivity are very sensitive. It can burn in an oxygen-free environment, and may explode under normal impact or friction. Therefore, in the solid propellant mechanical test, in the design and manufacture of uniaxial specimens, the general method is to first pulp a single material, mold and demold. The model can be a general rectangular block, and then cut with a ceramic knife, or it can be directly used for the corresponding model of the specimen. However, in the design and manufacture of biaxial / triaxial specimens, since the specimen is too complex, the corresponding model cannot be used for demolding, which will make the internal cavity too large and the experimental results invalid. Manual cutting with a tool is also not allowed, because manual cutting cannot ensure the pairwise neutrality of the six axes, which will turn the tensile test into a shear test, affecting the test results.
