Development of an Undergraduate Structural Dynamics Laboratory

该项目包括开发设备和实验，用于向本科工程师讲授动态载荷条件下结构的行为。 实验室的开发增强了现有实验室的可用设施，用于教授结构在静载荷下的行为。 测试从简单的自由振动实验开始，展示如何测量表征运动的动态参数，然后通过受到动态力（例如，风载荷）或基础运动（例如，地震）引起的受迫振动的结构，以及减振技术的应用（例如，通过使用阻尼器和基础隔离器）。 大多数实验都会使用小型结构，但至少在一个实验中，学生将评估现有原型结构的动态性能。 进行此类测试的总体目标包括：（1）使学生了解动态结构行为和相关理论； （2）教授学生使用现代动态测试设备和数据采集设施； (3) 作为一种动力并丰富他们的教育经验。 仪器将提供最先进的体验，而且易于使用。 可以进行的实验基本上是无限的，并且可以进行更改以满足不断变化的课程需求，而无需额外费用。

This project encompasses the development of equipment and experiments for teaching the behavior of structures under dynamic loading conditions to undergraduate engineers. The laboratory development augments the facilities available in an existing laboratory which is used to teach behavior of structures under static loads. Tests begin with simple free vibration experiments demonstrating how dynamic parameters characterizing motion are measured, progressing through structures subjected to forced vibration caused by dynamic forces (e.g., wind loads) or base motion (e.g., by an earthquake), and application of vibration reduction techniques (e.g., by use of dampers and base isolators). Small-scale structures will be used in most of the experiments, but in at least one experiment, the students will evaluate the dynamic performance of an existing prototype structure. The overall objectives in conducting such tests include: (1) enabling the student to understand dynamic structural behavior and related theories; (2) teaching the students the use of modern dynamic testing equipment and data acquisition facilities; and (3) serving as a motivational force and as a general enrichment of their educational experience. Instruments will provide state- of-the-art experience and yet will be easy to use. The experiments which can be performed are essentially unlimited and can be changed to meet changing curricular needs at no additional cost.
