Missile body charge friction environment simulating device

Abstract

The invention discloses a missile body charge friction environment simulating device. The missile body charge friction environment simulating device comprises a friction barrel, a sleeve, a sample, strain sheets, an end cover, a force transmission column, simulative explosive powder and a base, wherein the end cover is mounted at one end of the force transmission column, the other end of the force transmission column is embedded into the inner cavity of the friction barrel, the sample is arranged inside the inner cavity of the friction barrel, the simulative explosive powder is arranged inside the cavity on both sides of the sample, and the sample and the simulative explosive powder are both tightly arranged inside the inner cavity of the friction barrel. The strain sheets are symmetrically arranged on the outer wall of the friction barrel; one end of the friction barrel, which is away from the end cover, is mounted inside the sleeve; one end of the sleeve, which is away from the end cover, is mounted inside the base; the force transmission column, the friction barrel, the sleeve and the base are coaxially arranged. The missile body charge friction environment simulating device has the advantage of being capable of simulating a real missile body charge friction environment, small in measuring error, simple in structure and low in cost and labor intensity.

Description

technical field [0001] The invention belongs to the technical field of propellant and explosive experimental devices, and relates to a frictional environment simulation experimental device, in particular to an experimental device for simulating the frictional environment of projectile charging and serving. technical background [0002] The interior of the projectile is filled with high-energy explosives. During service (high-speed penetration, armor-piercing, etc.), the explosives will be subjected to complex stresses such as compression and friction, and "hot spots" may be formed locally, resulting in early explosion. To the predetermined technical and tactical goals. Therefore, the safety of projectile charging during service has become a focus of attention of weapons and equipment research and development departments. At present, the adiabatic compression environment of projectile charges in service can be simulated through large-scale drop weight loading devices and hig...

Problems solved by technology

However, there are few reports on the simulation of the frictional environment during the charging of projectiles.

[0003] In the Chinese invention patent "A Frictional Load Loading Device" with the publication number CN 102706224 A and the publication date of 2012.10.03, the method of rapid friction between one end face of the explosive tablet and the surface of the friction column is used to simulate the friction environment of the projectile charge , the main problems are: (1) The contact area between the explosive and the friction column is very small, and only one end of the explosive bears the friction load, which brings a certain measurement error to the test results

(2) Different from the real service environment of the projectile charge, there is no strong restraint device around the explosive in the friction load loading device, the heat generated by friction will be dissipated quickly, and the surface temperature of the friction column before friction with the explosive is always Room temperature, which affects the formation of explosive "hot spots"

(3) The installation process of the device is complicated, the assembly precision is high, and the labor intensity is high
