A Master&rsquo;s thesis explored how mathematical simulation might help understand these oscillations—not by solving the problem definitively, but by building a theoretical model to investigate the mechanisms.</p> <p>This post examines that exploratory work: how a two-degree-of-freedom mathematical model, implemented in MATLAB, can be used to investigate stick-slip behavior and explore potential mitigation approaches. The emphasis is on <em>methodology</em> and <em>investigation</em>, not on solutions proven to work in practice.</p>
