【 摘 要 】

The computer analysis of the influence of flexspline materials at the strength of the flexspline was performed for two and three dimensional models using the finite element method and MSC Patran/Nastran software. Calculations were conducted in two steps. The first one concerns two dimensional models on the contact between the flexspline and the wave generator. The second concerns three dimensional models of flexspline. The application of steel and steel-composite materials as material of the flexspline in harmonic drive was analysed. In calculations were used two types of composites with an epoxy resin, reinforced by the carbon-fiber or the glass-fiber. The preliminary study of stresses for the developed models was made. The steel-composite hybrid flexspline as compared to conventional steel flexspline showed a decrease of maximum stress in the analyzed dangerous cross-sections. Shapes and the frequency of vibration of the flexsplines were also calculated. The impact of stacking fiber angle on the frequency of vibration in the tested flexsplines is negligible.
