Data Acquisition and Computer Simulation Integrated Experiment for an Undergraduate Machine Dynamics Laboratory
A cam-follower mechanism experiment is described that involves the calibration of several mechanical transducers and computerized data acquisition. Laboratory measurements are followed by modeling the experiment using multi-body simulation software (VisualNastran 4D and Working Model 2D). Students compare their simulations with the measured results and learn about the benefits of integrating physical experiments with virtual experiments. Their confidence in the results obtained through simulation, as well as their preference for performing either one of both type of experiments are surveyed.
This paper describes an experiment that has been developed for the Machine Dynamics course in the University of Tulsa’s Mechanical Engineering Department. This four-credit hour, junior level course contains six laboratory experiments as follows: Operating point of a battery powered sweeper - apparatus was custom made; Free and forced vibration analyses of a single degree-of-freedom system using a TM16 apparatus from TQ Education and Training Ltd.1; Static and dynamic balancing of rotating masses using a TM102 apparatus from TQ Education and Training Ltd.2; Flexible rotor dynamics experiment - apparatus was custom made as senior-design project; Experimental analysis of a cam follower mechanism - apparatus was custom made as a senior-design project3 and retrofitted to work with LabVIEW4 data acquisition software.
