Research and Analysis on the Fiber Bundle Tension Impacting the Strength of Flywheel with Composite Material

The tensile strength of the flywheel,which is of composite material,is much higher than that of normal metal material.But the low radial shear strength is one of the most important factors for increasing the rotary speed.Based on the 3D numerical module and finite element analysis software,this paper studies 3 D calculation of the rotary speed of composite material flywheels,and analyses how the fibre bundle tension force impacts the strength of the rotor.
