Finite Element Analysis of Fully Equivalent Stress of Pressure Field & Thermal Field for Gun Barrel of Composite Material

建立了复合材料身管连续射击时的边界条件和有限元模型。对复合材料身管在连续射击过程中火药燃气压力和火药燃气温度场的动态全等效应力及其分布进行了数值仿真,所得到的结果,为复合材料身管的应用提供了一定的参考。

In this paper the firing boundary conditions and finite element model of composite barrel un- der burst firing are established.Numerical simulation of the fully dynamic equivalent stress of powder pressure & thermal field under burst firing and its distribution in the composite barrel is carried out.Results obtained can be as references for application of composite barrel.
