摘要
飞轮储能装置是一种在电能和机械能之间进行能量转换的装置,它通过飞轮高速旋转的形式来储存能量。普通机械轴承由于摩擦阻力,飞轮储存的能量有很大一部分耗散在此处。设计的新型磁悬浮轴承可以有效降低摩擦阻力,从而提高飞轮储能效率。对飞轮系统的搭建及部分机械系统进行了完整的设计,并完成了样机产品的测试。此装置可以应用到机械类和电类专业本科生的工程实践教学中,以PBL项目驱动的教学方式,使学生深入理解产品设计原理、制造技术、装配调试方法等。
Flywheel energy storage device is a device that converts energy between electrical energy and mechanical energy.It stores energy in the form of high-speed flywheel rotation.Due to the friction resistance of ordinary mechanical bearings,a large part of the energy stored in the flywheel is dissipated.This article introduces a new magnetically suspended bearing,which can effectively reduce the friction resistance and improve the energy storage efficiency of the flywheel.The flywheel system and the mechanical system are designed,and the prototype product is tested.This device can be applied to the engineering practice teaching for mechanical and electrical majors.With the PBL project driven teaching method,students can master the product design principle,manufacturing technology,and assembly and debugging methods.
