Abstract

The invention discloses a vehicle body analysis method under a muzzle shock wave effect, terminal equipment and a medium, and the method comprises the steps: obtaining a computational domain model which comprises a geometric model of a vehicle-mounted artillery; carrying out muzzle shock wave flow field simulation calculation on the computational domain model, and obtaining pressure distribution borne by the vehicle body surface of the vehicle-mounted artillery at different moments; according to pressure distribution borne by the vehicle body surface of the vehicle-mounted artillery at different moments, carrying out pressure remapping on the geometric model of the vehicle-mounted artillery, and obtaining a target grid model; and performing vehicle body impact influence analysis on the target grid model to obtain an analysis result of the vehicle body key component in the vehicle-mounted artillery. By adopting the invention, the technical problems of low analysis precision, long calculation time, resource waste and the like in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a vehicle body analysis method under the action of a muzzle shock wave, a terminal device and a medium. Background technique [0002] With the continuous increase of the country's military strength, the military's demand for multi-functional combat vehicles is becoming more and more urgent. How to evaluate the impact of the muzzle shock wave on the body protection has become an urgent problem to be solved. Among them, the firing of the artillery relies on the combustion of the gunpowder gas in the chamber to drive the movement of the projectile. Before and after the projectile exits the muzzle, a complex flow field of high temperature and high pressure will be formed around the muzzle, which directly acts on the cab at a relatively short distance through transmission. Due to the large area of ​​the vehicle cab and the thin skin, under the action of the muzzle shock wave close t...
