The Nonlinear Dynamics and Vibration Laboratory
The Nonlinear Dynamics and Vibration Laboratory (NDVL) researches system identification and structural health monitoring in nonlinear systems, nonlinear feedback control for enhanced sensitivity in damage detection and sensing, analyzing the dynamics of nonlinear piecewise-linear systems, bifurcation forecasting, and turbomachinery modeling and analysis. The two key research thrusts are (1) the creation of techniques to efficiently model, analyze, and exploit nonlinearity, and (2) the analysis of complex high-dimensional cyclic structures found in turbomachinery. To aid in the analysis and experimentation of turbomachinery the NDVL is partnered with the Gas Turbine Laboratory (GTL) at The Ohio State University. The work at the GTL focuses on full scale industrial turbomachinery operating at engine speeds. The NDVL is focused on more fundamental research such as creating tools for analyzing and exploiting nonlinear dynamics, with the goal of investigating some of these tools in the GTL with industrial hardware to accelerate industrial partners’ usage of these tools. The research that is being conducted can be broken into general nonlinear dynamics and structural dynamics of turbomachinery.
The NDVL is always looking for exceptional undergraduate and graduate students to work on a variety of projects related to structural and nonlinear dynamics. Projects range from computational and theoretical work to hands-on experimental work related to dynamics and vibration.
Undergraduate students please look for openings and apply through the undergraduate research placement tool.
Graduate students please reach out to Professor D'Souza at his university e-mail address. Please include a current resume/CV as well as a cover letter addressing your interests and goals.
