摘要/Abstract

摘要： 飞轮储能密度是衡量转子材料结构技术水平的重要指标,分析了储能密度的计算方法和工程制约因素,提出了一种简要的工程计算方法,并应用于一文献所给出的飞轮结构的储能密度分析和校核.目前我国的实验飞轮线速度没有超过800 m/s,储能密度小于60 W·h/kg.

关键词: 飞轮储能, 储能密度

Abstract: Energy storage density is an important technical specification for the structure and materials design of flywheels. In this paper, theoretical analyses are carried out on the energy storage density of flywheels. Limiting factors on increasing energy storage density of flywheels are identified and analyzed. A simple correction method is put forward for the calculation of energy density of flywheels and data from the literature are used for the validation of the method. Currently, experimental flywheels in China have a linear velocity below abut 800 m/s with an energy density below 60 W·h/kg.

Key words: flywheel energy storage, stored energy density
