An expedited research and development effort is proposed to formulate a nonlinear control theory of rotating shafts and chains. There will be three components to this effort: (i) We shall extend our recent work on the nonlinear stability theory of buckling in rotating shafts and chains to obtain a sharper picture of the way in which buckling depends on both design parameters such as mass distribution and shaft stiffness and also on the angular velocity profile of the rotation. (ii) Taking account of the nonlinear dynamics of these systems, we shall draw on recent work in nonlinear control theory to lay the theoretical foundations for active control of buckling. (iii) We shall design an experimental facility to support and guide future theoretical research in the control of rotating mechanisms.

建议加快研究和开发工作， 旋转轴和链条的非线性控制理论。 会 这一努力的三个组成部分：（一）我们将扩大我们最近的 研究旋转轴屈曲的非线性稳定性理论 和链条，以获得更清晰的图片， 取决于设计参数，如质量分布和轴 刚度以及旋转的角速度分布。 (ii)考虑到这些系统的非线性动力学，我们 将利用非线性控制理论的最新研究成果， 屈曲主动控制的理论基础。(iii)我们将 设计一个实验设施，以支持和指导未来 旋转机构控制的理论研究。
