TITLE: Back to the Basics, Masses and Springs and What They Teach Us About Vibrationasics, Masses and Springs and What They Teach Us About Vibration

SPEAKER: Dr. M. Austin Creasy

About Our Speaker:

M. Austin Creasy, Ph.D. is an associate professor in the School of Engineering Technology at Purdue
University. He is the Mechanical Engineering Technology (MET) program lead where he leads the
curriculum and assessment committees that define the content of the MET program. He has taught
20 different courses during the 12 years as a faculty member of Purdue that include content related
to mechanics, materials, and programming. Dr. Creasy has over 35 published articles in journal and
conference proceedings. He is currently a member of the Board of Directors of the Vibration Institute
(VI) and is leading the efforts in providing VI training online

SUMMARY:  A mass and a spring are the fundamental unit that allows us to understand a lot about vibrating systems.  A vibrating system contains oscillating force, mass, stiffness, and damping.  A mass and a spring make a system where these four items can be easily manipulated to understand their individual relationship on a vibrating system.  That understanding allows us to develop equations that we can use to model a system and predict how that system will react to changes.  This presentation will discuss the vibration of a mass and spring, show how math models are derived, and show how models can be manipulated to understand vibration.A mass and a spring are the fundamental unit that allows us to understand a lot about vibrating systems.  A vibrating system contains oscillating force, mass, stiffness, and damping.  A mass and a spring make a system where these four items can be easily manipulated to understand their individual relationship on a vibrating system.  That understanding allows us to develop equations that we can use to model a system and predict how that system will react to changes.  This presentation will discuss the vibration of a mass and spring, show how math models are derived, and show how models can be manipulated to understand vibration.
