| 摘 要： | 针对火炮发射过程中构件的弹性和构件间的阻尼效应导致的有功内力问题，从力学的基本概念出发，推导了有功内力对应的广义力计算公式，为火炮发射动力学计算中公式符号的简化提供了理论依据，具体分析了火炮发射系统中存在的非刚性元件，如反后坐装置和上架、下架之间的摩擦力矩的有功内力问题，为解释火炮发射动力学的理论计算误差奠定了基础。

| Abstract: | In view of the problem of working internal forces caused by the elasticity of parts and the damper between parts in the firing process, based on the basic concepts of mechanics, this paper presents the deduced formula for the general force of working internal forces. The formula provides a theoretical basis for simplifying mathematical formula symbols in the gun firing dynamics. The internal forces concerned with the non-stiff parts such as recoil mechanism and the friction torque between upper carriage and lower carriage are studied. This paper lays a foundation for explaining the errors in the theoretical calculation of gun firing dynamics. |
