摘要

工程力学动力学课程是机械和土木工程等专业中最具挑战性的课程之一。但很少有大学敢于引入项目,通过构建自己动手的物理原型,进行测量和计算来提高学生对工程的好奇心,兴趣和参与度,以争夺最佳表现。本项目旨在以简单的方式引入复杂的多自由度振动问题,即应用于类地震振动的调谐质量阻尼器(TMD)的主题。这种类型的项目直接解决了工程与技术认证委员会(ABET)推荐的所有七项学生成果。该项目通过设计和建造类似建筑的结构及其相应的TMD原型,培养批判性思维和探究技能;在一定约束条件下进行试验,测试初始位移后的衰减;应用开源免费软件绘制和测量欠阻尼振荡;主要振动参数计算;以及将表现结果与其他团队进行比较。学生们通过对关键TMD参数的反复试验来解决这个复杂的调谐问题,这一策略在过程中激发了乐趣和赌博,并为衰减效率的最佳表现而竞争。直接观察学生的表现、学生调查、报告、演示视频、办公时间和访谈的数据表明,学生在所有项目阶段都积极响应,理解TMD的功能,并以比没有这种类型的项目更有意义的方式欣赏工程动力学的价值。

The Tuned Mass Damper as a Subject in Engineering Mechanics Dynamics
The course of Engineering Mechanics Dynamics is one of the most challenging courses for both mechanical and civil engineering programs, among others. But few universities dare to introduce projects to enhance students' curiosity, interest, and engagement toward engineering by constructing do-it-yourself physical prototypes, making measurements, and calculations to compete for the best performance. The intention of this project is to introduce a complex multiple-degree-of-freedom vibration problem in an easy manner, namely, the topic of a tuned mass damper (TMD) applied to earthquake-like oscillations. This type of projects directly addresses all seven student outcomes recommended by the Accreditation Board of Engineering and Technology (ABET). The project develops critical thinking and inquiry skills by designing and constructing the prototype of a building-like structure and its corresponding TMD; conducting an experiment under certain constraints to test the attenuation after an initial displacement; applying an open-source freeware to plot and measure underdamped oscillations; calculating main vibration parameters; as well as comparing performance results with another teams. Students approach this complex tunning problem by trial-and-error of key TMD parameters, a strategy that sparks fun and gambling to the process and competition for the best performance in attenuation efficiency. Data from direct observation of students' performance, student surveys, reports, presentation videos, office hours, and interviews showed that students enthusiastically responded at all project stages, understood the TMD functioning, and appreciated the value of dynamics in engineering in a more meaningful way than it would be without this type of projects.
