The Stress Analysis On The Main Part Of The Composite Storage Flywheel Rotor

As the international energy situation is getting severe, the requirement of clean and efficient energy storage devices become increasing, so that the flywheel energy storage technology continues to be concern. High-speed rotating flywheel energy storage is a devices, which makes the composite flywheel rotor to store energy:takes the electrical energy into mechanical energy to store up when charging, and converts mechanical energy into energy to output when discharging. high efficiency and environment friendly make the composite flywheel an ideal storage equipment.Composite flywheel is a high-tech-intensive product, which includes mechanics of composite materials, electronic circuit technology, magnetic levitation technology, control technology and other technologies in one direction. Solving the strength of the flywheel main part-the composite materials, is the problem of the flywheel rotor energy storage technology in a difficulty. This paper for the purpose of improving the main strength of the composite flywheel rotor, as the main means of ANSYS software, establishments the flywheel rotor macro model and mesoscopic model, to get a well program of prestressed filer winding process and the improvement measures of the production, for the composite flywheel rotor manufacture reference.The main innovation of this paper is combine the temperature difference method and the element deletion method in one model, to simulate the process of filer-wound, and ultimately to establish a well program of prestressing. Meanwhile, the establish the suitable mesoscopic model for an analog composite winding, curing, rotating, to simulate the real case of composite flywheel rotor production process, with the ingenious combination of the temperature difference method and the real loading temperature.
