This project uses NSF provided equipment to experimentally investigate the nonlinear oscillatory behavior of structures. The equipment, a dynamic signal analyzer, collects data from physical structures undergoing vibration tests. Nonlinear oscillations have been studied extensively in the past. These studies have focused on long term time response, the behavior exhibited long after transients have decayed. This project investigates how the motion evolves during the decay of the transients. Two projects benefit from the use of the equipment. The first focuses on the vibration of a cantilevered beam. Theoretical claims have been made for the potential of dangerous vibrations for certain types of disturbances. This project will attempt to substantiate these claims. A second project is concerned with rotating systems where theoretical claims have also been made for serious nonlinear behavior. These claims will be investigated through experimentation.

该项目使用NSF提供的设备进行实验 研究结构的非线性振动行为。 的 设备，动态信号分析仪，收集数据，从物理 正在进行振动测试的结构。 非线性振荡具有 在过去被广泛研究。 这些研究集中在 长期时间响应，表现出长时间后瞬态的行为 已经腐烂了 这个项目研究了运动是如何演变的 在瞬变的衰减期间。 两个项目受益于 设备的使用。 第一个重点是振动 悬臂梁 理论上， 潜在的危险振动的某些类型的干扰。 本项目将试图证实这些说法。 第二 项目涉及旋转系统，理论上要求 也有严重的非线性行为。 这些索赔 将通过实验进行研究。
