中文摘要： 车载飞轮电池是一种高速磁悬浮储能飞轮，可作为驱动电动汽车的唯一或辅助能源。但是磁悬浮轴承存在涡流和磁滞损耗，不利于飞轮能量长时间保存。更为重要的是，高速飞轮转子在汽车行驶时将产生大小与方向不断变化的陀螺扰动力矩和惯性力并且转速变化范围大，导致磁悬浮轴承不能完全克服陀螺扰动力矩和惯性力的冲击，容易造成高速飞轮转子与磁悬浮轴承碰撞。本项目拟在低损耗磁悬浮轴承技术和飞轮转子的减振方法与机理两方面进行深入研究。提出变偏置电流方式，研究同极型结构和变偏置电流方式对降低磁悬浮轴承损耗的效果；引入金属橡胶隔振器，研究结构参数优化设计，以充分发挥金属橡胶隔振器和磁悬浮轴承各自的优点，有效减轻磁悬浮轴承的负担；提出并研究基于转速与变偏置电流方式的自调整模糊控制策略对车载飞轮电池系统动态性能的影响。本研究的目的是解决车载飞轮电池的碰撞问题并进一步减少其自放电，推动车载飞轮电池在电动汽车上的应用进程。

英文摘要： Flywheel Battery for vehicle is a kind of flywheel energy storage system supported by Active Magnetic Bearing and can be used for the only or auxiliary energy source for vehicle. However Active Magnetic Bearing will cause eddy current loss and hysteresis loss, so flywheel energy is difficult to be storaged for long time. More importantly, flywheel rotor with high and wide-range rotation speed will cause gyroscopic torque and inertial force with variable magnitude and direction which Active Magnetic Bearing can hardly bear when vehicle is running, so flywheel rotor is easy to run into Active Magnetic Bearing. The project will aim to further investigate low loss Active Magnetic Bearing and vibration attenuation mechanism of flywheel rotor. In the project, Variable Bias Current Control is advanced and the influence of homopolar structure and Variable Bias Current Control on power loss of Active Magnetic Bearing will be studied. Metal Rubber Isolator is introduced into Flywheel Battery for vehicle and structural parameter optimization design will be studied so that Metal Rubber Isolator and Active Magnetic Bearing can give the best use and the load of Active Magnetic Bearing is lightened. Self-Tuning Fuzzy Control strategy based on rotation speed and Variable Bias Current Control is also advanced and its influence o
