船载火炮发射时船体的有限元分析

地面火炮在远洋地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时的应和具有非常重要的，该文依据有限元方法的基本理论，建立了地面火包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，得到了不同工况下体最大应力的位置及其应力值，为使用远洋拖网渔船载火炮并在航渡中发挥火力的战方安节参考依据。

A Finite Element Analysis of the Hull of an Oversea Trawlboat under Gun Shooting

When field artillery shooting 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 strain of the ship body and the gun shooting platform on the gun's firing.A finite element model of the hull of a trawlboat under field gun shooting 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 maximum stress and strain as well as their position are derived under different condition,thus providing important reference to the operational scheme of making full use of the firepower when the field artillery sailing on board of an oversea trawlboat.
