| 摘 要： | 研究了由于弹丸加速运动在身管中激发的振动问题。通过将身管简化为一悬臂梁，弹丸的作用简化为一加速移动的载荷，建立了身管的运动方程，求得了级数形式的解析解，给出了一个算例并作了详细讨论。

| Abstract: | This paper deals with the linear dynamic response of a gun including the effect of the gravity of projectile and its acceleration.By considerring the gun project as a cantilever under an accelerately moving force,the equation of motion of guntube is eshtablished and a series solution for the dynamic deflection in terms of normal modes is obtained.A variety of numerical results is given and been discussed. |
