A Pseudo-Rigid-Body Model for Large Deflections of Fixed-Clamped Carbon Nanotubes

摘要: Carbon nanotubes (CNTs) may be used to create nanoscale compliant mechanisms that possess large ranges of motion relative their device size. Many macroscale contain elements are subjected fixed-clamped boundary conditions, indicating they value in design. The combination conditions and strains yield deformations at the tube ends strain stiffening along length tube, which not observed analogs. large-deflection behavior a fixedclamped CNT is well-predicted by beam bending models or truss models. Herein, we show pseudo-rigid-body model adapted capture and, thereby, predict CNT’s with less than 3% error from molecular simulations. resulting set initial design parameters for CNT-based mechanisms. This removes need iterative, time-intensive simulations during phases. DOI: 10.1115/1.4001726
