基于Workbench的多级轮盘组件优化设计

摘要

In order to improve performance of the wheel disk,a multi physical field optimization platform for thermal and structural coupling was established based on Workbench and integrated optimization software optiSLang.The optimization design of weight reduction for multistage disks assembly was carried out. The results show that the stress and deformation of the disks at all levels meet the design requirements after optimization.The reserve of disk's meridian plane was uniform distribution and the material utilization was improved.The low-pressure turbine disks totally lost 4.45kg weight, which achieve the desired goal. The optimization platform is two dimensional optimization platform based on disk's meridian plane,which can be used in the concept design stage,and provide the technical reserve for establishing a more detailed three-dimensional optimization platform.%为了改善轮盘的性能,基于Workbench与集成的优化软件optiSLang建立热与结构耦合的多物理场优化平台,对多级轮盘组件进行了减质优化设计.结果表明:优化后各级轮盘应力及变形满足设计要求,子午面应力储备分布均匀,提高了材料的利用率,低压涡轮盘质量共减轻4.45 kg,达到了预期目标.本优化设计平台为基于轮盘子午面的2维优化平台,可用于轮盘方案阶段的设计工作,为建立更为详细的轮盘3维优化平台提供技术储备.
