We have conducted a variety of relatively small-scale experiments with the goal of illuminating interesting nonlinear behavior. Below is a gallery of the equipment we use in our laboratory.
Shake Table – The principal workhorse for the group's dynamical experiments involve the use of this shake table, which has a frequency range from 0 to approximately 3Hz.
Shake Table – The shake table platform.
Shake Table – The scotch yoke amplitude mechanism.
