Acoustics and Dynamics Laboratory

This research laboratory is concerned with the analysis, design and synthesis of automotive and mechanical transmission systems for reducing noise, shock and vibration; development of inter-relationships between dynamic forces and motions in rigid or elastic machine elements; study of complex acoustic sources and transmission paths; techniques for passive and active noise control; and digital signal processing for sound quality, system identification, and diagnostics. Since most mechanical systems exhibit significant nonlinearities associated with clearance nonlinearities (such as backlash and multi-staged springs), dry or sliding friction, finite amplitudes, etc., nonlinear dynamic studies are emphasized. Refer to the journal publications where over 240+ articles have been posted; these provide specific information on the knowledge generated.
