Dynamic Resonances in Mechanical Systems

项目负责人/机构：Donald Dane Quinn university of akron提案编号：0084162标题：机械系统中的动态共振探索性研究（SGER）项目将用于开发一种实验性多组分结构，该结构由于与各种组分相关的动力学耦合而表现出依赖于系统状态的共振。随着时间的推移，所提出的耦合系统将缓慢地进入和退出共振状态，例如在多叶片涡轮盘中遇到的现象。该设施的成功完成将使研究人员能够开发用于实现捕获这些复杂系统相关耦合动力学的降阶模型和方程的工具。如果成功，拟议的项目还将推动开发工具，用于捕获复杂动态耦合的替代模型，例如由间歇性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.
