About Me
I am currently pursuing my Doctoral studies at The Ohio State University. I work as a Graduate Research Associate at the Gear and Power Transmission Laboratory, under the guidance of Dr. David Talbot. My current research is in the field of Multibody dynamics with elastic contacts, primarily dealing with the "Load Distribution and Dynamic Behavior of Planetary Gear Systems." As part of my research, I perform both experimental and theoretical investigations to study the behavior of planetary gear sets. My research interests include; Multi-Body Dynamics, Non-linear Dynamics & Chaos, Mechanical Meta-Materials, NVH, and Human body motion. I am passionate about what I do and look forward to collaborating with like-minded people to improve my knowledge and contribute to the advancement of the field.

A dynamic load distribution model of planetary gear sets
L Ryali, D Talbot
This study presents, a three-dimensional dynamic load distribution model of planetary gear sets, which can capture the influence of several component and system level design variations. A numerical integration scheme is used in conjunction with an iterative elastic contact algorithm to solve the multibody dynamics problem. This approach inherently captures the mesh stiffness fluctuation, without the need for an empirical mesh stiffness formulation or transmission error excitation of the system. The unique dynamic response of the parametrically excited system under various gear mesh phasing conditions is studied using the proposed model. Influence of gear tooth modifications and carrier pin position errors on the dynamics of the gearset is explored, also a brief study to demonstrate the model's capability to capture contact non-linearities in the case of low contact ratio gear sets is included. Discussed results not only illustrate the validity and potential of the proposed dynamic model but also reinforce the need for such computationally efficient models for design purposes.
