摘要: 在建立了叶片与轮盘三维装配模型的基础上, 考虑了由于装配产生的接触应力与叶片轮盘之间的耦合作用后, 建立了叶片-轮盘装配耦合的振动特性计算的有限元模型.并采用ANSYS软件, 使用循环分析方法对某叶片轮盘耦合结构的振动特性进行了计算分析.通过模态实验校验的手段证明用这种方法进行榫接装配系统动力学分析是可行的.

Abstract: While a 3D assembly model of blade-disc structure was established,a finite element model for calculating the vibration characteristics during blade-disc coupling was set up by taking into consideration of the coupling action of contact stress between blade and disc.With the help of ANSYS software,the vibration characteristic of blade-disc coupling structure was calculated and analyzed using cycle analysis method.Through modeling experiment,this method is proved to be feasible for analyzing the rabbet assembly structure.
