摘要：
A novel dynamic model for rotating pre-twisted carbon nanotubes reinforced composite (CNTRC) blades with elastic boundary constraints is established based on the first-order shear deformation theory (FSDT). The effects of Coriolis and centrifugal forces are considered in the formulation. Based on the Euler-Lagrange equations, the natural frequencies and vibration modes of a rotating pre-twisted blade are obtained. The model's accuracy is verified by comparing it with the results in the literature and Ansys. The influence of distributions of CNTs, pre-twist angle, rotation speed, and stagger angle on the vibration of the ceramic matrix CNTRC blade is studied in detail.
