Description

technical field The invention relates to a test device for missile launching equipment, in particular to a test device for simulating and evaluating the dynamic mechanical characteristics of a missile metal braking cone buffer. Background technique In the missile launch test, the metal brake cone was used as a buffer to protect the internal launching mechanism of the missile from being damaged by the gas momentum or rushing out of the box after the missile was separated from the launch box. In order to ensure the reliable operation of the weapon system, the dynamic mechanical characteristics of the metal brake cone of the buffer mechanism need to be simulated and assessed. At present, the known simulation test devices for metal brake cones as buffers mainly use gas electric squibs or gas gunpowder to test the dynamic mechanical characteristics of brake cones. Although there is no problem with the authenticity of the simulation, there is a risk that the work site will be mor...
