The Three-dimensional Finite Element Analysis About Gear of Turbine Engine's Gearbox for UAV

建立某无人机用涡喷发动机减速器齿轮系的三维有限元模型和齿轮啮合模型,利用该模型进行了瞬态模拟计算,得到了电机齿轮与小齿轮、大齿轮与主传动齿轮啮合过程的瞬态应力分布和安全系数,为减速器齿轮系结构的设计和分析提供了理论依据。该齿轮系已成功应用于某型涡喷发动机的减速器,强度满足要求,这种基于ANSYS的三维瞬态有限元分析可为其它齿轮传动结构的分析提供借鉴。

The three-dimensional finite element model about gears of turbine engine＇s gearbox for UAV has been established based on ANSYS and the meshing course between gears has been simulated.Further more,the instantaneous stress distributions and safety factors about running gears has been calculated and these gears have been succeeded in using to some turbine engine＇s gearbox.The method based on ANSYS and 3D model provided a theory to design and analysis for gears,it also uses to other gears.
