Pacific Southwest Section Meeting Paper Submissions
Undergraduate engineering dynamics often lacks a concrete connection between methods learned and hands-on engineering applications. We tried to create a stronger link between real life problems and theory through the use of motion capture technology. This paper focuses on the use of six pre-defined experiments to introduce students to using motion capture technology to analyze the kinematics and kinetics of real life situations. Students chose from gait, an elliptical machine, rowing, trebuchet, bike, and a Geneva mechanism to analyze. They used the live motion capture technology in the Human Motion Biomechanics Lab (HMBL) at California Polytechnic State University to obtain positional data. Using a provided spreadsheet which utilized first and second order finite difference method differentiation, students calculated velocities and accelerations for their problem. Students compared their analytical solution to the numerical solutions from the acquired data, and proposed reasons for variations. In a post-activity survey, 63% of students said the assignment helped them visualize concepts, while 95% of students said that they think aspects of the HMBL should be incorporated into future sections.
