通过光弹实验表明了端齿连接转子受力的分区循环对称性。针对这一特性建立了各循环对称分区的循环对称接触有限元应力分析方法,并利用叠加原理将各循环对称分区间过渡区化为几个小规模的循环对称问题。
The experiment of photoelasticity shows the circulation symmetry of the end teeth connected with the rotor. Aiming at this characteristic, the cyclic symmetry contact finite element stress analysis method for each symmetrical zone is established, and the superposition principle is used to transform the transition zone between symmetrical zones into several small-scale circular symmetry problems.
