Design and Simulation of Continuous Variable Inertia Flywheel
The flywheel is the most commonly used energy storage component in mechanical energy stor-age systems.The moment of inertia of a conventional flywheel is fixed,making it difficult to balance the de-mands for high energy storage capacity and fast response.To address this issue,a flywheel device that can con-tinuously adjust the moment of inertia within a certain range of speeds is proposed in this paper.This device a-chieves variable moment of inertia by radially arranging movable mass blocks on the flywheel.Additionally,the inner and outer hydraulic cylinders,as well as dual check valves between them,are set up to control the resist-ance when oil flows in both directions,thereby adjusting the critical value of the rotational inertia change rate.A simulation model was established using MATLAB software,and further analysis of the adjustment principle and characteristics of the flywheel device has been conducted,and key design points have been identified,providing theoretical guidance for conducting detailed engineering design.
