The working principle of the device for releasing the internal stress by the elastic deformation of the wavy spring piece is as follows:
the high-energy fuel expands with heat and contracts with cold, generating internal stresses sufficient to cause the casing to crack, in this embodiment the volume of the scattering device 3 filled with high-energy fuel is not fixed, but varies. The wave spring piece 2 moves upwards, the high-energy fuel loading volume is reduced, the wave spring piece 2 moves downwards, the high-energy fuel loading volume is increased, and the wave spring piece 2 is determined according to the internal stress of the high-energy fuel during moving up and down. That is to say, the volume of casing can relax the internal stress according to the corresponding regulation volume of expend with heat and contract with cold of high energy fuel, protection casing safety. Meanwhile, air is not arranged in the shell, and when the explosive is exploded and thrown, the air is not compressed to generate high temperature, so that only fuel and air are available in the process of forming cloud cluster by the outward movement of the high-energy fuel, the high temperature is not available, and the three burning factors are not satisfied, so that fire cannot be leaped. And the explosive explosion part has high temperature and air but no high-energy fuel, and the three elements of the fuel are not satisfied and the fire cannot be leaped.
The material design of wave spring leaf 2 is spring steel, mainly considers wave spring leaf 2 needs the up-and-down motion to warp, needs to have good resilience.
The upper end surface and the lower end surface of the second concentric circular plate of the wave spring piece 2 are wavy from outside to inside, and the wave spring piece 2 is mainly used for further improving the up-and-down deformability of the wave spring piece 2 through the optimized design of the shape.
The inside of the scattering device 3 contains high-energy explosive, and high-energy fuel can be driven to form a cloud cluster after explosion.
The upper end face of the first lower end concentric circular plate of the lower end arched shell 1 is provided with a first annular bulge, the lower end face of the first lower end concentric circular plate of the lower end arched shell 1 is provided with a first annular groove, the design is made, so that the first lower end concentric circular plate of the lower end arched shell 1 is provided with an upward arch, the space of the arch is used for filling high-energy fuel, and the wave spring piece 2 at the lower end of the arch moves upwards and downwards to adjust the volume.
The wall thickness between the first annular bulge and the first annular groove of the lower arched shell 1 is equal, so the design is mainly to reduce the influence of the first annular bulge and the first annular groove of the lower arched shell 1 on the throwing of the high-energy fuel to form a cloud shape, because the cloud shape directly influences the explosive power, the best cloud shape is a flat cylinder, and the wall thickness is equal so that the restraint on the lower end of the high-energy fuel is uniform.
In the arcs at two ends of the axial section of the first annular bulge of the lower end arched shell 1, the arc curvature radius far away from the rotation axis of the lower end arched shell 1 is twice of the arc curvature radius close to the rotation axis of the lower end arched shell 1, and the design is carried out in order to reduce the influence of the first annular bulge and the first annular groove of the lower end arched shell 1 on the scattering of the high-energy fuel to form a cloud cluster shape, because the cloud cluster shape directly influences the explosive power, the best cloud cluster shape is a flat cylinder, and the fuel moves outwards along the radial direction after being subjected to the explosive scattering effect of the scattered explosives, and the design is carried out in such a way, so that the resistance of the first lower end of the lower end arched shell 1 to the outward movement of the circular plate is reduced to the minimum, and the cloud cluster shape is not influenced.
In tests, the wall thickness between the first annular bulge and the first annular groove of the lower end arched shell 1 influences the shape of a cloud cluster formed by throwing the high-energy fuel, the shape of the cloud cluster directly influences the explosion power, the best shape of the cloud cluster is a flat cylinder, if the wall thickness between the first annular bulge and the first annular groove of the lower end arched shell 1 is too thick, the restraint on the lower end of the fuel exceeds the upper end to form the upper-lower asymmetry of the cloud cluster, and similarly, when the wall thickness between the first annular bulge and the first annular groove of the lower end arched shell 1 is too thin, the restraint on the lower end of the high-energy fuel is lower than the upper end to form the cloud cluster or the upper-lower asymmetry, so that the subsequent high-energy fuel explosion power is not favorably exerted.
Through partial theoretical calculation, the staff who summons relevant working experience consults the discussion collectively, and decomposes the above technical problem, and each module carries out experimental evaluation alone, and final experimental, evaluation result shows, the ratio of the wall thickness between the first annular bulge and the first annular groove of lower extreme arched shell 1 to the first lower extreme concentric circular plate thickness of lower extreme arched shell 1 is 1: 1.3-1.5, the above technical problems can be avoided. Therefore, the device for releasing the internal stress through the elastic deformation of the wavy spring piece of the embodiment has the advantages of being capable of embodying the design and playing the function well, and the technical problem can be solved well by using the device for releasing the internal stress through the elastic deformation of the wavy spring piece of the embodiment.
In this embodiment, the ratio of the wall thickness between the first annular protrusion and the first annular groove of the lower arched shell 1 to the thickness of the first lower concentric circular plate of the lower arched shell 1 is 1:1.3;
