Abstract

The invention relates to a storage test device for simulating a stress effect of a medicine column of a solid engine. The device is composed of a propellant strain device and a video monitoring system. The propellant strain device comprises a base, a supporting rod, a positioning rod, a fixing rod, a lower clamp, an upper clamp, and a positioning bolt. The adjustment of the distance between the upper clamp and the lower clamp is realized through the positioning rod, a positioning ring, the positioning bolt, a fixing nut and a positioning nut, so that continuous adjustment of the tensile displacement of the propellant is realized. According to the storage test device and method for simulating the stress effect of the medicine column of the solid engine, the stress condition of the medicinecolumn of the engine can be simulated, the performance change and damage condition of the propellant under the action of force is monitored, the performance degradation condition of the propellant under the comprehensive stress condition is evaluated, a test method is provided for the service life evaluation of the engine charge, and the data support is provided for improving the service life evaluation of the engine.

Description

technical field [0001] The invention relates to a storage experiment device and method for simulating the stress of a solid engine charge, in particular to a storage performance experiment device and method for an engine under the stress of a propellant, and is applied to the technical field of life evaluation of strategic and tactical solid engines. Background technique [0002] Most of the time after the solid engine is made, it is in a storage state. The solid engine is not only affected by combat readiness environmental factors such as temperature, humidity, and air pressure, but also by platform carrying environmental factors such as overload shock, temperature shock, rapid pressure change, and swing vibration. These comprehensive factors finally act on the solid engine in the form of stress. In actual storage, as long as the metal shell of the engine is not rusted, its mechanical properties will not change significantly. As long as the shell of the composite material i...
