Abstract

Carbon nanotubes (CNTs) exhibit exceptional mechanical properties, making them highly promising for various applications. This study conducts dynamic modal analysis on single-walled carbon nanotubes (SWNTs) to explore their vibrational behavior and natural frequencies. Findings indicate a consistent decrease in natural frequencies with increasing nanotube length under cantilever and bridge boundary conditions, attributed to increased mass requiring more vibrational energy. In contrast, nanotube diameter shows inconsistent effects on natural frequency. Results suggest that SWNT natural frequency is more influenced by length than diameter. The study provides valuable insights for designing devices and structures using SWNTs, proposing short SWNTs for high-frequency resonators and long SWNTs for high-performance applications. Overall, this research enhances our understanding of SWNT dynamic characteristics, offering crucial information for the development of innovative nanoscale technologies.
