Acoustics, Dynamics and Vibration

Nonlinear Modeling of Electrodynamic Systems

Research in Acoustics, Dynamics and Vibration track is directed at the many challenging problems associated with the design and operation of modern engineering structures, ranging from development of fundamental theory and innovative computational tools to application-based research into topics such as offshore structures, vehicles, ground-borne vibration and musical instruments. We have access to extensive computational and experimental facilities, and we have close ties with industry, research and other academic institutions. Research expertise of our faculties lies in areas related to structural vibration, vibration control, noise control, acoustics, stability, bifurcation & chaos, pattern formation, non-smooth systems, time-detailed systems.

Research Areas

  • Linear and nonlinear modeling of electrodynamic systems

  • Anti lock braking system, Traction control system & Electronic stability control
