摘要:: 用有限段法计算高炮身管的弹性变形 ,用基于Kane方程的Huston方法建立了某高炮 7刚体 18自由度的多体系统动力学模型 ,对高炮发射过程进行了数值仿真 ,计算得出的炮口角位移明显大于不计身管变形的 5刚体 10自由度模型的计算结果。 2种模型计算出的炮箱后坐曲线是完全一样的 ,与实测的炮箱后坐曲线一致 ,证明了上述分析的正确性 ,为高炮精度分析提供了更严格的理论参考

Abstract:: T he f inite segment method is used for computing the elastic deformation of an ant iaircraf t gun barrel. The dynamic model of the gun with 7-rigid-body and 18 degrees of f reedom is established by means of Huston’ s method based on Kane. s equations. The numerical result s show that the angle displacement of the muzzle is larger than that of the dynamic model w ith 5-rigid-body and 10 deg rees of freedom. The gun-chest back-lash curves figured out by the tw o models are ex act ly consistent, and they are in agreement w ith the measured curves, w hich proves that the abovement ioned analysis is right, thus prov iding a more strict theoret ical inference for the precision analysis of the ant iaircraf t.
