将火炮简化为悬臂梁,考虑剪切变形、回转惯性力矩、火炮后坐加速度、弹丸惯性力矩和陀螺力矩等的作用,得火炮身管横向振动的二阶偏微分联立方程。可用于确定内膛弯曲度、身管热变形、弹丸偏心率、内弹道诸元和身管结构等对射弹散布的影响。 The artificial cantilever simplified as a cantilever beam, consider the shear deformation, inertial moment of rotation, artillery recoil acceleration, projectile moment of inertia and gyroscopic moment of the role of the gun and so on, the second-order partial differential equations governing the lateral vibration of the barrel. Can be used to determine the curvature of the bore, tube heat distortion, projectile eccentricity, internal ballistic elements and tube structure on the projectile dispersion.
