The purpose of this experiment is to introduce students to principles in structural dynamics through the use of an instructional shake table. Natural frequencies, mode shapes and damping ratios for a small scale structure will be obtained experimentally through a series of tests. In the first test a sine sweep is applied to the structure to determine the frequency response function of the structure. The frequencies are identified, and a sinusoidal excitation is applied to examine the mode shapes. Next the damping in the system is estimated using two techniques and the results are compared. Students will use a Matlab GUI program to obtain experimental data of the structure and analyze the data.
