The aim of the project is to design passive and active control strategies to suppress the discontinuity-driven catastrophic loss of stability of recurrent motions in a mechanical system that occurs due to low-velocity collisional contact with the environment. Specifically, passive and active changes in the system parameters characterizing the collisional discontinuities will be exploited to prevent a global transition to high-velocity impacting motions associated with increased noise production, fatigue failure, and derailment of tracked vehicles.
