CLASSIFICATION OF NANOBEARINGS AND MATHEMATICAL FORMULATION OF THEIR OPERATION

Nanomechanical systems necessitate components with unparalleled precision and minimal frictional resistance to achieve optimal performance. Nanobearings represent a critical class of components that facilitate rotational or linear motion at the nanoscale. This paper presents a comprehensive classification of nanobearings, encompassing their structural attributes, materials employed, and operational mechanisms. Additionally, it provides a detailed mathematical formulation that describes the static and dynamic behavior of nanobearings, including equations for load capacity, friction torque/force, and stiffness. Numerical examples illustrate the application of these mathematical models in analyzing the performance of diverse nanobearing types. The findings provide invaluable insights for designing and optimizing nanobearing-based devices utilized in a wide range of applications spanning precision engineering, microfluidics, and biomedical engineering domains. This expanded version delves deeper into the significance of nanobearings in nanomechanical systems and highlights the crucial role they play in enabling precise and low-friction motion at the nanoscale. It also emphasizes the importance of the mathematical formulation presented in understanding and predicting the behavior of nanobearings, which is essential for designing and optimizing nanobearing-based devices for various applications. © 2024 International Multidisciplinary Scientific Geoconference.
