The flywheel battery is a new type of electromechanical energy conversion and storage devices, with a large reservoir of energy, high-power, non-polluting, high efficiency, widely applicable, no noise, long life and other advantages, has a broad application prospects. It is mainly composed of high-speed flywheel rotor magnetic bearing systems, electric / generator, the machine is a typical electromagnetic integration products. Their research involves multidisciplinary machinery, materials, electrical, thermal, computer, and mostly in the research prototype device has not been systematic and in-depth research, design theory and methods, rotor vibration research car maglev flywheel battery a new issue, this paper pavement incentive rotor vibration of the car maglev flywheel battery proposed mathematical model and its numerical simulation. The first chapter describes the research background and significance, lists flywheel battery works, structural composition and performance, research status and application prospects, the main content of the thesis. Chapter II automotive system model with seven degrees of freedom. Detailed derivation from a theoretical analysis to the establishment of differential equations and write the stiffness matrix, damping and mass matrices. The third chapter is divided into three parts. PD control car maglev flywheel battery the rigid rotor mathematical model, focused the flexible rotor mathematics Quality Act simplified model based on the theory of vibration specific solving method listed on the mathematical model of rigid and flexible rotor. Chapter maglev flywheel battery car rigid rotor time-domain simulation using MATLAB software instance data; followed by application of a concentrated mass flexible rotor modal simulation; final application Riccati transfer matrix method for car flywheel battery elastic support simplified single-disk flexible rotor the modal vibration simulation. Chapter V of the full text of the study work summarizes the main findings and conclusions are given, and the analysis of the main innovations of the paper, pending further study. Car maglev flywheel battery is an application promising new green power battery, of papers its rotor vibration, both theory and technical difficulty, there are very important scientific research value.
