摘要：Thispaper examines the influence of various geometric configurations of flywheelson kinetic energy storage performance using finite element analysis.Historically flywheels have been used in various applications. From suchapplications as pottery wheels to steam engines, flywheels have been used tostore mechanical energy. Currently, in the ever expanding world of green energydevelopment, flywheel energy storage systems provide an alternative source ofenergy storage that does not harm the surrounding environment. But when itcomes to overall efficiency, e.g., manufacturing, reduced energy loss, inproviding energy to the public, there is always a need for a more costeffective energy storage system. As such, this paper analyzes various geometricconfigurations of flywheels for the purposes of utilization as an energystorage source alternative. In particular, this is focused on the fact thatreducing the amount of materials needed to produce the greatest amount ofenergy, i.e., high energy density, is needed for a flywheel energy storagesystem. In the analysis, the key parameters for each flywheel configuration areconsidered to examine the flywheel energy storage performance. These parametersare polar moment of inertia for determining the energy capacity of theflywheel, the shape factor for each cross section and maximum stress in theflywheel with its corresponding maximum angular velocity for each crosssection. With all analytical results in terms of those parameters, an optimalflywheel system will be determined.
