为保证整体叶盘结构在安全工作条件下质量最轻,基于ANSYS优化平台,建立了整体叶盘三维参数化模型及结构优化设计数学模型,完成了整体叶盘结构的优化设计.首先结合相关静强度设计准则及方法,在给定轮缘分布载荷条件下对轮盘子午面进行优化.然后建立整体叶盘三维模型,并对子午面优化中未考虑的轮缘关键尺寸如轮缘厚度、喉道倒角、叶根倒角进行三维局部优化.在三维优化中总结出了盘喉道和叶根最大等效应力与各优化参数之间的关系.分两步实施的整个轮盘优化过程仅需3～4h.
In order to ensure the lightest quality of leaf disc structure under safe working conditions, a three-dimensional parameterized model of leaf disc and a mathematical model of structural optimization design were established based on ANSYS optimization platform, and the optimal design of the leaf disc structure was completed.Firstly, Strength design criteria and methods to optimize the wheel meridian under a given rim load distribution.After that, a three-dimensional model of the whole leaf disc is established and the key factors that are not considered in the meridian optimization, such as rim thickness, Chamfering, chamfering of root and three-dimensional local optimization of chamfering.The relationship between the maximum equivalent stress of disk throat and root and the optimization parameters is summarized in three-dimensional optimization.The whole roulette optimization process implemented in two steps Need 3 ~ 4h.
