摘要

针对宽弦空心风扇叶片余量分布不均匀甚至负余量的困难,提出了考虑壁厚与外形耦合约束的多层次余量优化方法。首先,获取外形在机测量结果后,利用拉普拉斯网格变形算法重构叶片毛坯曲面,据此在叶片机内测量允用时间内获得壁厚测量处精确的法矢。为了加工余量分布同时满足叶身壁厚和外形的设计要求,建立了耦合壁厚和外形的优化约束条件,提出了不同解空间的多层次余量优化变量,从而构建了不同优先级的余量优化模型。并且通过递进使用不同优化模型求解最优空心叶片余量分布。最后,以某型空心叶片为对象验证了所提方法的有效性,能保证加工余量、壁厚与外形耦合的公差约束,这为宽弦空心叶片智能余量优化提供了新方法。

Abstract

To address the problem of non-uniform and negative allowance distribution of wild-chord hollow fan blades, a multi-level allowance optimization method which considers the coupling constraint of wall thickness and profile is proposed. Firstly, in term of the profile measurement result by on-machine measurement, the blade blank surface is reconstructed by the Laplace mesh deformation to obtain the accurate normal vectors of wall thickness measurement in a short time. To make the machining allowance distribution meet the design requirements of the wall thickness and profile, the optimization constraint which couples the wall thickness and profile are established, and the multi-level allowance optimization variables with different solution spaces are achieved, so as to construct allowance optimization models with different priorities. Furthermore, different optimization models are used to get the optimal hollow blade allowance distribution. Finally, the proposed method is verified by the experiment which takes a certain type of hollow blade as the object, and the experiment ensures the tolerance constraints of machining allowance, wall thickness and profile coupling, providing a new method for intelligent allowance optimization of wide-chord hollow blades.
