Abstract/Artist Statement

The objective of this project was to design and fabricate a three degree of freedom dynamic model with a data collection system and a user friendly interface. This involved creating both physical and data acquisition systems. The physical system contains two masses constrained to three degrees of freedom. A cart is one of the masses and is capable of translating back and forth while the second mass consists of a pendulum that can rotate as well as elongate via a spring. The data acquisition system consists of a microcontroller that has the ability to receive and interpret raw positional data while simultaneously controlling a linear actuator. The demand for this project came from the lack of current in-class demonstrations for Kinematics and Vibrations courses. Specifically, there is a need to provide visual representation of course concepts which support student learning. The three degree of freedom model will allow students to compare data output to theoretical predictions. The project has met all goals by delivering a high quality assembly that mitigates frictional factors, allows for repeatable forcing, collects data that can be compared to theoretical expectations, and allows for portability. This project will provide a demonstration tool that can be used in the classroom to reinforce kinematic and vibrational concepts.
