Abstract
The long-term goal of this work is to demonstrate the power of a new method in machine dynamics that engages students and inspires innovation. The short-term objective is to exploit Lorentz force effects to create a liquid gyroscope to assess orientation. This is a transdisciplinary educational project at the intersection of mechanical engineering, electrical engineering, design, and manufacturing to create the prototype. The project used Galinstan, a liquid metal alloy consisting of gallium, indium, and tin, to create the liquid metal gyroscope. When exposed to a magnetic field and an electrical current, Galinstan displays unique behavior, resulting in the formation of vortex-like patterns. This study aims to investigate the potential of utilizing this phenomenon for gyroscopic applications. This project is student conceived, initiated, and conducted based on inspiration from the Moving Frame Method (MFM) in Dynamics. The MFM is a new approach to machine dynamics that simplifies the discipline, by leveraging Lie Group Theory and Algebra (distilled to the simplicity of matrices), Cartan’s sense of moving reference frames and a compact notation. First, this paper briefly summarizes the MFM and how it stimulates student learning in an era of disengagement. Then this paper launches into a description of the concept, design, and construction of the liquid gyroscope. This paper discusses the difficulties of achieving precise control, stability, and practicality such as turbulence in the liquid corrosion and magnitude of the magnets. The project recognizes the need to understand fluid dynamics, chemistry mechanics, as well as electro mechanics to overcome these challenges and advance the concept of a liquid metal gyroscope. This current investigation is exploratory and provides insight into the potential applications and practical experience within the field.
