Elastodynamic and Acoustic Response of High-Speed MechanicalSystems

机械系统性能的提高意味着实现更低的成本，同时保持或提高最终产品的质量。还需要提高效率、寿命和可靠性。系统的振动水平和随之而来的噪声辐射是提高速度和负载重量比的两个限制因素。这个项目是一个多学科的努力来研究高速机械系统的弹性动力学和声学响应。采用凯恩法对机构弹性构件的总体动力特性和振动响应进行了建模。声辐射公式基于亥姆霍兹积分。该模型将为机械系统的设计、综合、优化和诊断研究提供有价值的设计和研究工具。

Improved performance of a mechanical system means achieving less cost, while maintaining or improving the quality of the end product. Increased efficiency, longevity and reliability are also needed. Vibration level of the system and consequent noise radiation are two limiting factors on hiqher speeds and higher load to weight ratios. This project is a multi-disciplinary effort to examine the elastodynamic and acoustic response of high speed mechanical systems. It models the gross dynamic behavior and vibration response of the elastic components of the mechanism using Kane's method. The acoustic radiation formulation is based on the Helmholtz Integral. The model which evolves from this study will be a valuable design and research tool for use in the design, synthesis, optimization, and diagnostic studies of mechanical systems.
