Dynamic Resonances in Mechanical Systems

PI/机构：Donald Dane Quinn University of AkronProposal编号：0084162标题：机械系统中的动态共振这个探索性研究(SGER)项目将用于开发一种实验性的多组件结构，由于与各种组件相关的动力学的耦合，该结构显示的共振取决于系统的状态。所提出的耦合系统将随着时间的推移缓慢地进入和离开共振状态，例如在多叶片涡轮盘中遇到的现象。这一设施的成功建成将使人们能够研究开发工具来实施降阶模型和方程，以捕捉这些复杂系统的相关耦合动力学。如果成功，拟议的项目还将取得进展，导致开发工具来捕捉复杂动态耦合的替代模型，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.
