Abstract

In a multidisciplinary Engineering Technology (ET) program with 5 different concentrations, it is not possible to cover the detailed theory and applications of all high-level classes. For this reason, many educational projects are aimed to give students the opportunity to acquire this high-level knowledge through a hands-on practice. At the end of these projects, students conclude their experience and prepare a student manual that, later on, guides other groups in getting the same knowledge through hands-on experience. This initiative is applied through some senior design projects within the Engineering Technology program. In this paper, a shaking table is used to learn the concepts of (1) vibration analysis, (2) vibration absorber design (that is usually covered in Mechanical Vibration class which is not currently offered at our ET program), and (3) elastic material property evaluation of metals and non-metals (including 3D printed parts) through experiments. A Shake Table II, made by QUANSER, a MakerBot Replicator+ 3D printer, two 352C33 accelerometers, and a 2-channel ICP signal conditioner, are used in these experiments. Structures made from different metals and 3D printed materials are designed and built to simulate Single Degree of Freedom (SDOF) parameters and dynamic behavior. Vibration absorber are designed and tested through experimentations. Elastic properties such as Young’s Modulus, equivalent spring stiffness, and natural frequencies are evaluated through different experiments. The wok is documented and experiment manuals are generated. This is a leading effort in creating learning modules for subsequent students to learn by experiments which can be added as a lab module in upper level classes.
