减速器齿轮箱拓扑优化及轴承有限元分析

Topology Optimization of Reducer Gearbox and Finite Element Analysis of Bearings

以某公司生产的减速器齿轮箱为例,利用Solidworks建立齿轮箱的三维模型,根据齿轮箱实际受力情况确定其边界条件,利用ANSYS软件对齿轮箱进行静力学和动力学分析。基于ANSYS软件对齿轮箱进行结构拓扑优化设计,并对优化后的齿轮箱模型进行有限元分析,对比其结构优化前后的结构性能参数。最后对优化后的齿轮箱圆锥滚子轴承进一步进行静力学分析,得到其运动状态。对结果表明,优化后齿轮箱正转和反转时静态性能分别提高了60%和85%左右,动态性能提高了16%左右,大幅提高了齿轮箱的结构性能;圆锥滚子轴承在齿轮箱正转的情况下工作状态正常,验证了齿轮箱运行安全。

Take the reducer gearbox produced by a company as an example,first establish a three-dimensional model of the gearbox,determine the boundary conditions of the gearbox when it is working,and use ANSYS Workbench software to establish its finite element analysis model,and perform static and dynamic analysis on the model.Secondly,based on the ANSYS Workbench software,the gearbox is designed for topology optimization,and the optimized model is analyzed by finite element static and dynamic analysis,and it’s compared that the structural performance parameters of the reducer gearbox before and after optimization.Finally,the optimized tapered roller bearing of the gearbox is analyzed statically,and its motion state is obtained.The result shows that after optimization,the static performance of the gearbox is increased by about 60%and 85%in forward and reverse rotation,and the dynamic performance is increased by about 16%,which greatly improves the structural performance of the gearbox;The tapered roller bearing works normally when the gearbox is rotating,which verifies the safe operation of the gearbox.
