Linear and Nonlinear Dynamics and Vibrations Laboratory

The Linear and Nonlinear Dynamics and Vibrations Laboratory (LNDVL) at the University of Illinois was formed as the result of a merger, in 1998, of Dr. Alexander Vakakis's and Dr. Lawrence A. Bergman's own laboratories. With the addition of Dr. Michael McFarland to the group, and with the assistance of the Departments of Mechanical Science and Engineering (MechSE) and Aerospace Engineering, the College of Engineering, support from federal and industrial sponsors, and numerous graduate and undergraduate students the Laboratory has evolved to its present state.

Current research thrusts include the use of passive nonlinear targeted energy transfers for aeroelastic instability (flutter) suppression, seismic mitigation and vibration and shock isolation of mechanical and structural components; dynamics of non-smooth dynamical systems (with emphasis to vibro-impacting systems and systems with friction); nonlinear system identification and reduced order modeling; structural health monitoring and damage detection; structural acoustics; and theoretical studies of dynamical systems and bifurcations in multi-dimensional systems.
