This paper discussed the strength criterion of composite firstly. Then the strength condition of the high speed energy storage flywheel was put forward. In the paper the calculation model of the limiting rotational speed of flywheel based on strength has been established using the finite element analysis and the optimization method. As an example, a typical composite flywheel in hybrid electrical vehicle flywheel battery was calculated. The limiting rotational speed and the stress distribution on such situation were obtained. This method provided an effective way for design and development of flywheel.
