本文描述了在火箭推力作用下，中间集中质量对悬臂柱动力稳定性的影响。假设火箭推力是由在具有中间质量的悬臂柱的尖端安装固体火箭发动机产生的。假设火箭发动机是一个具有有限尺寸但没有质量点的刚体。理论和实验证明了中间质量的大小和大小的重要性。考虑了火箭发动机的质量和尺寸以及中间质量效应，将实验结果与理论预测结果进行了比较。在理论预测中忽略了内部阻尼。结果表明，理论稳定性预测与实验颤振极限吻合较好。
The paper describes the effect of an intermediate concentrated mass on the dynamic stability of cantilevered columns subjected to a rocket thrust. It is assumed that the rocket thrust is produced by the installation of a solid rocket motor at the tip end of the cantilevered columns having the intermediate mass. The rocket motor is assumed to be a rigid body having finite sizes but not a mass point. The importance of the magnitude and size of the intermediate mass is demonstrated by theory and experiment. The experimental results are compared with theoretical predictions made by taking into account the mass and size of the rocket motor as well as intermediate mass effect. The internal damping was neglected in the theoretical predictions. It is shown that theoretical stability predictions and experimental flutter limits agreed well.
