| 摘 要： | 针对火炮发射过程中身管受载的复杂性，以内弹道方程为基础，考虑发射过程中身管受载的实际规律，计及身管的柔性效应，建立描述身管振动响应规律的动力学方程组。采用模态叠加法，以身管的固有振型为模态函数，对动力学方程进行离散，联立内弹道方程进行数值求解，给出了发射过程中身管的频率响应和振动特性分析，为火炮总体性能整合和射击精度分析提供了理论参考。

| Abstract: | Under the action of different kinds of load,the gun tube will produce complex elastic vibration in the process of projectile lanuch,and it has important effect on fire precision of projectile.Aimed at the complexity and real law of loads on gun tube in the process of projectile lanuch,based on the interior ballistic equations,taken account of the flexible effect of gun tube,the dynamic coupling equations that describe the vibration response law were established.By use of modal superposition method,taken the... |
