在EU－QLID-IS软件上模拟了双环减速器中内齿板在传动过程中的啮合情况，并对内齿板的受力状况进行了分析研究，建立了13种工况下的内齿板的有限元分析计算模型。利用NASTRAN软件求出各模型的应力及变形分布变化规律，找出最危险的工况，对内齿环板的强度状况进行了研究，为提高双环减速器整机性能设计提供了有力的依据。
In the EU-QLID-IS software to simulate the double-ring reducer internal gear meshing in the process of transmission, and the force of the internal tooth plate was analyzed and studied the establishment of 13 kinds of conditions under the internal tooth plate Finite element analysis and calculation model. Using NASTRAN software to calculate the stress and deformation distribution of each model, find the most dangerous conditions, the strength of the internal ring plate is studied, in order to improve the double ring reducer performance design provides a strong basis.
