Follow on Google News | Universities Use Vibration Exciters to Teach Concepts and Inspire InnovationModal shakers and electrodynamic exciters from The Modal Shop play key roles in university level vibration education.
By: The Modal Shop The Cooper Union for Advancement of Science and Art in New York City is an excellent example. Melody Baglione, Assistant Professor of Mechanical Engineering, purchased a 2100E11 modal shaker in 2009 followed by the addition of two new SmartShakers in 2010. Cooper Union students have put these vibration exciters to work. In the Advanced Mechanical Vibrations class, experiments were conducted using the 2100E11 shaker to determine the natural frequencies produced by plastic plates and aluminum cantilevered beams. Both applications provided students with an opportunity to evaluate the differences between theoretical natural frequencies and vibration modes versus those generated in a live, experimental setting. From these basic types of experiments, a group of Professor Baglione’s students moved on to a more complex form of experimental modal analysis. A scale model of a three story building offered the opportunity for a more realistic testing application. With accelerometers attached to each floor of the model and the 2100E11 modal shaker exciting the entire structure, the students collected data to analyze the effect of a mass damper on forced response. The Cooper Union’s use of vibration exciters is a perfect example of using real world test equipment as an integral part of an educational experience. Universities benefit from PCB Group and The Modal Shop’s long history of collaboration with educational institutions.
