摘要未来的作战环境决定了火炮必须具备快速反应能力，为适应现代战争快速部署需求，轻量化已成为火炮总体结构设计首要考虑因素之一。本文以某105mm坦克炮为设计对象，进行了轻量化设计与分析。为了达到火炮战斗全重技术指标和性能，在火炮总体设计中采用了零部件多功能化设计、零部件等强度/刚度设计、轻质材料应用等技术手段，在保证火炮功能性能下最大限度地减轻火炮质量。74516
本文利用Creo软件进行了火炮虚拟样机的总体设计，采用了高强度炮钢材料、轻质钛合金材料、摇架与反后坐装置一体化、双驻退双复进的结构使全炮质量减轻。并利用MATLAB软件进行了相关计算。接着利用ANSYS软件对轻量化设计后的摇架进行了受力分析与计算仿真。此外，本文还对轻量化的效果进行了分析。

Title Lightweight Design and Analysis of Artillery
Abstract The environment of modern warfare requires artillery to response rapidly, in order to deploy rapidly,lightweight design has become a key consideration of the general structure design of the artillery。 This paper regards a 105 mm tank gun as a design object for lightweight design and analysis。In order to achieve the combat-full-weight technical indexes and performance of the artillery,I used more functional design and constant strength/stiffness design of the parts as well as the application of lightweight materials in the general structure design of the artillery to reduce the weight of artillery furthest under the guarantee of its functionality。
In this paper, Creo software has been used in the structural design of the virtual prototype of the artillery, also I have adopted the high strength gun-steel material and titanium material,used structures of a integration of cradle and recoil mechanism device, the double recoil double compound to reduce the quality of the entire artillery。 And the related calculations are carried out using MATLAB software。 Then I used ANSYS to study the force analysis and calculation simulation of the cradle。In addition, this paper also analyzes the effect of lightweight design。
