Dr. Braj Bhushan Prasad is a researcher in vibroacoustics, structural dynamics, and vibration control, with a focus on developing innovative methods to mitigate noise and vibration in engineering systems. His work combines experimental investigations, numerical simulation, and data-driven analysis to understand and control complex dynamic behaviour in lightweight structures and propulsion-related components. His research has contributed to applications in electric mobility, renewable energy systems, and industrial machinery, particularly through the development and validation of particle damping technologies for passive vibration mitigation.
Dr. Prasad’s research integrates Finite Element Methods (FEM), Discrete Element Methods (DEM), and experimental vibroacoustic measurements to analyse vibration mechanisms and design effective damping solutions. His work includes collaborations with both academia and industry, contributing to projects involving electric propulsion systems, hydrogen-powered engines, and wind turbine structures. Through these efforts, he aims to bridge fundamental research with practical engineering applications that improve system reliability, acoustic performance, and structural durability.
More recently, he has begun developing an emerging research direction in aerospace vibroacoustics, particularly related to unmanned aerial vehicles (UAVs) and lightweight aerial systems. In this context, his research explores how vibration control strategies—such as particle damping and advanced structural analysis—can contribute to noise reduction, structural stability, and improved acoustic performance in future aerial platforms. This work is currently at an exploratory stage and aims to extend established vibration-control methodologies toward aerospace applications through interdisciplinary collaboration and new experimental approaches.
Overall, his research aims to advance sustainable and quieter engineering systems by combining physics-based modelling, experimental validation, and emerging computational techniques, including data-driven and AI-assisted analysis for complex vibroacoustic problems.
