Abstract
|
Artillery shells buried armored vehicles of the future direction of development of one of the guns , the paper as a engineering background , to carry out large-caliber artillery shells buried within the trajectory design and numerical simulation , the main contents are as follows : inspection and analysis of a large number of artillery shells buried abroad literature , based on the emission process for buried munitions work characteristics , carried out a bomb buried ignition simulations . With high-speed video recording system , observing the buried bombs in the guide tube ignition , sliding properties. On this basis, to establish an ignition bomb buried mathematical model and numerical simulation , theoretical calculations and experimental values ??agree well . In the 105mm artillery platform, launched a buried artillery ballistic missile firing tests . Ignition and combustion process using secondary concept , combining interior ballistics theory, a ballistic artillery shells buried zero-dimensional model and the one-dimensional aerodynamic model, using Visual Basic language program for the calculation software, 105mm ballistic missile buried process the numerical simulation obtained bore pressure, velocity and other parameters change over time and displacement characteristics . Calculated results agree with experimental data . Finally, buried artillery shells filled with internal ballistic performance parameters to predict the impact analysis .
