Dynamic Resonances in Mechanical Systems

主要研究者/机构：Donald Dane Quinn阿克伦大学提案编号：0084162标题：机械系统中的动态共振这一探索性研究（SGER）项目的小额赠款将用于开发一种实验性多部件结构，该结构由于与各种部件相关的动力学耦合而呈现出取决于系统状态的共振。 所提出的耦合系统将随着时间的推移缓慢地移入和移出共振状态，这是例如在多叶片涡轮机盘中遇到的现象。 该设施的成功完成将使调查的工具，用于实施降阶模型和方程，捕捉相关的耦合动力学这些复杂的系统的发展。 如果成功的话，拟议的项目还将推动开发用于捕获复杂动态耦合的替代模型的工具，例如由间歇接触和摩擦引入的模型。

PI/Institution: Donald Dane Quinn university of AkronProposal Number: 0084162Title: Dynamic Resonances in Mechanical SystemsThis Small Grant for Exploratory Research (SGER) project will be used to develop an experimental multi-component structure which exhibits resonances that depend on the state of the system due to coupling of the dynamics associated with the various components. The proposed coupled system will slowly move in and out of a state of resonance as time evolves, a phenomenon that for example is encountered in multi-bladed turbine disks. Successful completion of this facility will enable investigations on the development of tools for implementation of reduced-order models and equations that capture the pertinent coupled dynamics these complex systems. If successful, the proposed project will also enable advances that can lead to the development of tools for capture of alternative models of complex dynamic coupling, such as those introduced by intermittent contact and friction.
