What is the nonlinear dynamic model of energy storage flywheel rotor?The nonlinear dynamic model of an energy storage flywheel rotor with SMA damper is established. A developed multi-scale method is proposed to obtain the natural frequency of the system with high accuracy in strong nonlinear condition, and the nonlinear dynamic characteristics of an energy storage flywheel rotor with SMA damper are analyzed.
Does a flywheel need additional damping?In the flywheel application, additional damping is needed since the eddy-current damping is low and may be inadequate for controlling transient vibrations, such as traversing a critical speed or dampening shock response.
What are the limitations of Flywheel design?One of the primary limits to flywheel design is the tensile strength of the rotor. Generally speaking, the stronger the disc, the faster it may be spun, and the more energy the system can store.
