不同模量比对复合材料储能飞轮强度的影响

Effect of Modulus Ratio on Energy Density of Composite Flywheel

以材料的环向与径向模量比λ作为参量,利用ANSYS有限元分析软件,对给定尺寸不同材料的单层及双层异构复合材料飞轮转子进行强度计算,得出飞轮转子在高速旋转时的径向和环向应力分布规律。进而利用强度比方程求解各种结构的强度比,分析材料参数对飞轮转子强度的影响。

The influences of Modulus ratio on energy density of composite flywheel was investigated.According to the finite element method,a given size of different materials for single-layer and double heterogeneous composite flywheel rotor stress was calculated.Obtained in high-speed rotating flywheel rotor radial and hoop stress distribution.And then solving the intensity ratio equation of various structures,analyze the material parameters on the strength of the flywheel rotor.
