Abstract

The invention particularly provides an internal trajectory high-speed friction force analogue simulation test testbed. The problem that an existing ammunition friction force test is obtained through calculation, so that the test precision is low is solved. A marking head and a high-speed camera are arranged on the outer side wall of a sleeve-shaped simulation gun bore, a linear bearing block is arranged on the sleeve-shaped simulation gun bore, a support I is arranged on a sleeve-shaped fuel cavity, a support II is arranged on a hollow oil pressure ejector rod, a piston is arranged in the sleeve-shaped fuel cavity, a piston ejector rod is arranged on the right end face of the piston, annular limiting blocks are arranged at the left end and the right end of the sleeve-shaped simulation gunbore, annular felt pads are fixed to the inner sides of the two annular limiting blocks, a hollow test projectile is arranged in the sleeve-shaped simulation gun bore, the hollow oil pressure ejectorrod communicates with the right end of the hollow test projectile, and multiple stress gauges are arranged on the outer column face of the hollow oil pressure ejector rod. The actual working conditionof the projectile under internal trajectory flight is simulated, and the high-speed friction of the internal trajectory under an internal trajectory can be directly obtained precisely.

Description

technical field [0001] The invention relates to a friction test device, in particular to a simulation test bench for internal ballistic high-speed friction simulation test. Background technique [0002] The friction of ammunition is a key technology that restricts the research and development of new ammunition. If you want to achieve technological breakthroughs in this type of ammunition, you must obtain the friction value of this type of ammunition. [0003] The friction force of this type of ammunition can be obtained by calculation, but the calculated values ​​are all obtained under theoretical assumptions, which are significantly different from the actual working conditions; The friction force of ammunition. Contents of the invention [0004] In order to solve the problem that the friction force test of the existing ammunition adopts calculation to obtain relatively high test accuracy, the invention provides a high-speed internal ballistic friction force simulation te...
