Dynamic Modeling Methods for the Design of High Performance Machines

高性能、高生产率的机器往往表现为振动过大、噪音大、可靠性和寿命低、精度差。需要新的分析方法来设计它们，以提高它们的性能。这个项目涉及更完整的，计算上实用的，动态分析方法的发展，为这些机器的设计。该研究涉及机器空间动力学、连接间隙的动力学影响、机器连接的分布质量和顺应性的动力学影响、支撑结构和外壳的动力学影响、制造中使用的紧固方法的影响以及控制系统和执行器。随着分析模型的发展，将对其进行实验检验。

High performance, high productivity machines often show excessive vibration and noise, low reliability and life, and poor precision. New analytical methods for their design are required to improve their performance. This project deals with the development of more complete, computationally practical, dynamic analysis methods for the design of such machines. The research addresses machine spatial dynamics, the dynamics effects of clearances in connections, the dynamics effects of distributed mass and compliance of machine links, the dynamics effects of supporting structures and enclosures, the effects of fastening methods used in fabrication, and control systems and actuators. The analytical models will be tested experimentally as they are developed.
