Problems solved by technology

[0004] However, due to differences in propellant powder, gun steel materials, and empirical coefficients in relevant calculation formulas in other countries, the method of designing single-barrel barrels using the third strength theory in other countries may not be suitable for my country. The outstanding problems are reflected in the selection of safety factors.

Embodiment Construction

[0064] The single-barrel barrel design of the gun is carried out after the internal ballistic design and calculation of the gun are completed. That is to say, when the barrel pressure curve of the barrel is known and the structural size of the inner bore of the barrel is known, the wall thickness of the barrel is designed to obtain the actual shape of the barrel.

[0065] 1. Calculate the high and low temperature pressure curve of the gun barrel.

[0066] High and low temperature pressure curves such as figure 2 As shown, the curve is composed of two straight lines and two curved lines, and the curve can be obtained by obtaining the endpoint data of the straight line and several points (more than 4) on the curved line.

[0067] two straight lines arrive straight line segment and arrive straight line segment; two curves refer to between data points and A curve segment consisting of data points between. Two straight line segments and two curved segments together f...

Abstract

The invention relates to a method for designing a gun monocular barrel based on a third strength theory. The method comprises the following steps of (I) calculating a high and low temperature pressure curve of a gun barrel; (II) calculating a theoretical strength curve of the barrel; (III) calculating a theoretical shape of the barrel; and (IV) adjusting the shape of the barrel. According to the method for designing the gun monocular barrel based on the third strength theory, the method for designing the gun monocular barrel in China is broadened, thereby being beneficial to exchange between China and various countries in the world in the aspect of gun monocular barrel design; and the method can be used for development of the gun monocular barrel in academies, scientific research institutes and weapon manufacturers.

Description

technical field [0001] The invention belongs to the field of weapon development and support, and in particular relates to a design method for a single barrel of a gun based on the third strength theory. Background technique [0002] The single-barrel barrel is currently the most widely used barrel for guns. Based on the influence of the former Soviet Union for a long time, the design of single-barrel barrels in my country adopts the second strength theory, and the design method is relatively mature. [0003] However, at present, not all gun barrel designs in various countries adopt the second strength theory. For example, European countries mostly adopt the third strength theory, and the United States mostly adopt the fourth strength theory. [0004] However, due to differences in propellant powder, gun steel materials, and empirical coefficients in related calculation formulas in various countries, the method of designing single-barrel barrels using the third strength theor...
