摘　　要：选用铝合金、钛合金和40Cr三种合金材料,分别分析每种材料在不同旋转角速度条件下的轮毂、轮缘的应力变化规律,利用有限元分析理论结合各向异性弹性体基本理论建立复合材料储能飞轮力学模型,借助ANSYS有限元分析软件,确定易于发生疲劳失效的部位;辅以相同转速条件下,飞轮转子径向和环向应力分析结果,得出铝合金在减小飞轮整体应力水平、优化储能密度方面均优于其他两种合金的结论,完善了选用轮毂材料的基本原则。Three alloy materials of aluminum alloy,titanium alloy and 40Cr are chosen,the stress change rule of hub and flange of ecah kind of material is analyzed based on different rotation angular velocities.The composite energy storage flywheel mechanical model is built with the finite element theory and the orthotropic elastic solid basic theory,with the finite element analysis soft ANSYS,the fatigue failure spot is found.With the same rotation angular velocity,and the analysis results of the flywheel rotor radial and circumferential stress,the final conclusion is got which the aluminum alloy is better than the other two alloys in reducing flywheel overall stress level,optimizing energy density,and improving the selection of the basic principle of wheel material.
