Centre for Vibration Testing and Analysis (CVTA)

About the Centre

The Centre for Vibration Testing and Analysis (CVTA) is an autonomous research and testing facility dedicated to the investigation, simulation, and mitigation of vibrations in mechanical systems and structural elements. Established to bridge the gap between academic knowledge and industrial application, the CVTA operates at the intersection of mechanical dynamics, condition monitoring, and structural health evaluation.

Our expertise spans vibration analysis, modal testing, noise–vibration–harshness (NVH) studies, and machinery diagnostics, addressing diverse sectors such as automotive, aerospace, civil infrastructure, and manufacturing

A key feature of the Centre is its emphasis on experiential learning. From the early semesters, students participate in hands-on vibration testing and simulation exercises using state-of-the-art tools, enhancing both analytical skills and industry readiness. The CVTA regularly organizes workshops, training programs, and technical seminars in collaboration with leading academic and industrial institutions, including IITs, NITs, and R&D organizations.

Through cutting-edge research, robust industry-academia partnerships, and continuous technology upgrades, the CVTA contributes significantly to advancements in vibration engineering and predictive maintenance.
