Acoustics and Dynamics Laboratory

This Hero Banner block does not have any unexpired Hero Banners. To display something here, configure this block to add a new Hero Banner, or adjust the expiration dates of existing Hero Banners.

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.
