|
摘要
介绍了齿轮试验检测平台及基础数据库建设的背景与意义,给出了一种锥齿轮闭功率流耐久性试验台结构方案,对试验台的结构组成、系统功能进行了分析阐述。基于Solid Works建立了试验台关键部件等速圆柱齿轮箱的三维模型,并导入ANSYS Workbench进行了有限元模型转换,根据试验台实际工作载荷,对箱体进行了静力学分析及模态分析,得出了箱体最大应力、变形量、固有频率、振型等,对啮合齿轮副进行了强度分析,表明等速圆柱齿轮箱满足设计要求。
The background and significance of gear test detection platform and basic database construction are introduced,and a structural scheme of bevel gear closed power flow durability test bench including the composition and system function is proposed. The 3 D model of constant speed cylindrical gearbox is established by using Solid Works 3 D software,the statics and modal of the box are analyzed according to the actual working load of the test bench by finite element method. The maximum stress,deformation and natural frequency of the box and the corresponding vibration mode are obtained,and the result of the strength check of meshing gears verify the constant speed cylindrical gearbox meeting design requirement.
