Project title: Optimal Energy Transfer in Nonlinear Systems
Supervisory Team: Daniil Yurchenko and Tim Waters
This is a unique project to study how energy transfer can be optimally performed between subsystems of a nonlinear system. The project output will have significant impacts in the area of vibration mitigation, vibration isolation and vibration energy harvesting.
Design and understanding of nonlinear models is required for optimal performance and for accurate reproduction of dynamical behavior. One of the intriguing phenomenon in nonlinear systems is Targeted Energy Transfer (TET), where the goal is to transfer energy within a nonlinear system between subsystems. The theory of linear dynamical systems is well-developed in the context tuned mass dampers, in contrast to nonlinear systems, where often individual nonlinear mechanisms are considered with a model-specific. A majority of these approaches rely on perturbation theory, which is valid, strictly speaking, for weak nonlinearities over finite time. TET is a nonlinear alternative that can also be generalized to multi-degree-of-freedom systems. In the traditional TET formulation, the nonlinearities are given for all degrees of freedom (for instance of cubic order), and the energy-transfer subsystem is tuned to an optimal set of parameters (coefficients) to mitigate undesirable dynamics of the primary system.
Based on the existing publications this leaves the following gaps in the TET’s state-of-the-art.
To address these gaps the project will combine machine learning optimization algorithms, such as Surrogate Optimization (SO) and methods in nonlinear dynamics.
This project will require a student with:
