The purpose of the Dynamics and Vibrations Laboratory is to support teaching and research activities in the dynamic study of mechanical systems, which occurs through dynamic modeling of the behavior of rigid and elastic bodies, interconnected and connected to elements outside the system by elastic and dissipative components, actuators and others. The result is non-linear mathematical models whose quality is guaranteed by numerical and experimental validations. The laboratory has and develops computational tools for this purpose and builds devices that allow validation techniques to be used. To this end, it has position, acceleration, force and moment sensors, actuators, motors, various mechanical elements, as well as data acquisition boards and programs for representing and analyzing this information. Recent applications: dynamic study of drilling columns, study of the stick-slip phenomenon in drill bits, dynamic study of systems with uncertain parameters, study of the control of devices with backlash and stick-slip, study of impacts in embedded systems, study of the rotational movement of bodies in rollover, etc.
