摘要
具有大范围、高速运动的柔性体,即使在小变形范围内,运动和变形的耦合将产生动力刚化现象.本文提出一种研究动力刚化系统新的方法,建立了求解动力刚化系统逆问题的数学模型,拓宽了动力则化问题的研究范围.该项研究对以柔性体为代表的航天器中的构件、机器人和高速机构等机械系统的设计、动力学仿真和减振控制,具有重要意义.
The flexible members undergoing large range and high speed motion have the phenomenon of dynamic stiffening due to the combination of motion and deformation of the structure,even if the deformation is Very small. In this paper,a new method is developed, which can be used iap the solution of inverse problems of dynamic stiffening system. And the range of dynamic stiffening problems is broadened. This study is very important for structure design and dynamic simulation and vibrlation absorber of modern mechanical systems including flexible members such as astronautic machine,robotic arms and mechanisms with high-speed motion etc.
