摘要
行星架是行星齿轮传动的关键性零件,行星架的自重、应力分布及形变量对行星齿轮啮合具有较大影响。为提高某型号风电齿轮箱行星架综合性能,基于响应曲面法进行拓扑优化,开展有限元分析,并以结构轻量化、减小最大Von Mises应力值及降低最大形变量作为优化目标,获得该型号行星架结构的最佳方案。最终拓扑优化结果表明,该型号行星架自重可降低2.35%,最大Von Mises应力值降低20.58%,形变量降低7.87%,行星架综合性能得到了改善。
Planetary carrier is a key part of planetary gear transmission.Its self weight,stress distribution and deformation have great influence on planetary gear meshing.In order to improve the comprehensive performance of a certain type of wind turbine gearbox planetary carrier,topology optimization was carried out based on response surface method,and finite element analysis was also carried out.The optimal scheme of this type of planetary carrier structure was obtained by taking the structural lightweight,reducing the maximum von Mises stress and reducing the maximum deformation as the optimization objectives.The final topology optimization results show that the self-weight of this type of planet carrier can be reduced by 2.35%,the maximum von Mises stress value can be reduced by 20.58%,the deformation can be reduced by 7.87%,and the comprehensive performance of the planet carrier has been improved.
