The objective of this project is to supplement classroom presentations of the fundamentals of mechanical vibrations with classroom demonstrations and laboratory measurements by students. Equipment and instrumentation are needed to excite and measure mechanical system response. Various spring-mass systems (with and without dashpots) will be built for use by instructor in the classroom and by students in the laboratory. The spring-mass will be simple models of one, two, and many degrees of freedom and will be designed to interface with theory. Equipment is needed to excite these systems in a controlled manner. Instrumentation is needed to measure the excitations and system responses. Major equipment includes a shake table, modal analysis system with fast Fourier transform analyzer, PC computer with printer and plotter, and accelerometers. Eight laboratory experiments are designed to support fundamental mechanical vibration theory. The project is significant because it gives a physical dimension to complex theory and exposes students to modern vibration measurement and analysis techniques.

该项目的目的是通过教室演示和实验室测量来补充机械振动基础的课堂演示。 需要设备和仪器来激发和测量机械系统响应。 将在课堂和实验室的学生中构建各种春季质量系统（带有和没有仪表盘）。 春季质量将是一个，二，多自由度的简单模型，并将设计为与理论接触。 需要设备以控制方式激发这些系统。 需要仪器来衡量激发和系统响应。 主要设备包括摇桌，具有快速傅立叶变换分析仪的模态分析系统，带打印机和绘图仪的PC计算机以及加速度计。 八个实验室实验旨在支持基本的机械振动理论。 该项目很重要，因为它为复杂理论提供了物理维度，并使学生接触了现代的振动测量和分析技术。
