某火炮制退机散热分析

Heat Dissipation Analysis of Gun Recoil Absorber

火炮的连续发射使制退机内液体温度不断升高,当温度达到制退液的沸点时,会导致后坐部分复进不到位,从而造成火炮的故障和损坏。针对这个问题建立了某火炮制退机简化模型,运用Ansys/Flotran软件对火炮的制退机进行散热分析,得出制退机的散热规律及温度分布。结果表明,该方法简单可行,构思新颖,为以后选取有较好散热性能的制退机材料提供依据。

As the temperature of gun recoil fluid rising continually through gun firing,the gun recoil fluid would reach to the boiling point.It might cause recoil parts failure of counter recoil to go forward,and made the gun in trouble or great damage.Aimed at this puzzle,the paper built a gun recoil absorber predigestion model,then made the simulation of heat dissipation analysis by ansys/flotran,and finally tried to know the recoil heat dissipation law and distribution of temperature.The result of heat dissipation analysis shows that it is feasible in simplification,and novel in design,and provides a method while choose the material of recoil absorber owned a better heat dissipating performance.
