摘要:
地面火炮在远洋拖网渔船上发射时对发射平台产生复杂的冲击效应 ,分析研究船体在火炮发射时的应力和应变具有非常重要的意义。该文依据有限元方法的基本理论 ,建立了地面火炮在渔船上发射时船体的有限元模型 ,并对多种射击工况进行了仿真计算 ,得到了不同工况下船体最大应力的位置及其应力值 ,为使用远洋拖网渔船载运火炮并在航渡中发挥火力的作战方案提供了参考依据。
Abstract:
When field artillery shoot ing on the platform fixed on a ship. s dock, a very complex shock effect is produced. It is of great importance to analyse the stress and st rain of the ship-body and the gun-shoot ing platform on the gun’s firing. A f inite element model of the hull of a t raw lboat under field gun shoot ing is established on the basis of the finite element theory. With this model, a series of numerical simulations are carried out under different conditions. The max imum st ress and strain as well as their posit ion are derived under different condit ion, thus prov iding important reference to the operat ional scheme of making full use of the f irepow er w hen the f ield art illery sailing on board of an oversea t raw lboat .
