某型大功率液力变速器行星架有限元分析及优化
|
摘要
利用UG精确地建立行星架的三维模型,运用ANSYS Workbench进行行星架的结构静力学分析,并以工艺孔直径和止推垫圈槽的结构尺寸为目标对行星架进行多目标驱动优化。并对优化后的结构进行模态分析,得到约束条件下各阶模态固有频率。与变速器位于四档时P1行星架的啮合频率进行对比,发现优化后的结构可以保证行星轮系的可靠性。
The accurate 3D model of the planet carrier was established by UG,structural statics analysis were carried out using ANSYS Workbench. Taking the structure size of thrust washer slot and the diameter of process hole as the target,Multi objective optimization was carried with the planet carrier. Through the modal analysis of the structure optimized,natural frequencies under different order modal were obtained. Compared with the meshing frequency of the planet carrier when the transmission is in fourth gear,the optimized structure can ensure the planetary gear train reliable.
