【摘要】 储能密度是复合材料飞轮结构设计的主要技术指标,为提高储能密度,必须选取比强度高的纤维复合材料并尽量提高飞轮的外缘线速度。该文探讨了考虑轴承、电机技术水平和可用材料等约束条件下的飞轮结构设计的一般方法,该方法应用于飞轮储能试验装置研制中,飞轮在试验中达到700 r/s,外缘线速度达到660 m/s,储能密度达到35W h/kg。更多还原

【Abstract】 A general design method was developed for high specific energy density(SED) energy storage flywheels.SED was a key characteristic of advanced energy storage flywheels.To achieve a high SED,high strength fiber reinforced plastic must be used and well designed as rims of flywheel.The design must also consider limitations such as the maximum bearing speed,motor capability,and materials strength.A composite flywheel prototype was designed and manufactured from aluminum alloy,glass fiber,and carbon fiber reinforced plastics.In high speed spin tests,the flywheel rotated at 700 r/s with a maximum peripheral speed of 660 m/s,and a specific energy density of 35 Wh/kg.更多还原
