摘要
以叶片叶身段为典型结构对象,分析研究了叶片精铸位移场模型中弯扭变形的分离方法,提出了变形矫正的计算方法,得到了弯扭变形分离后的位移场模型,为后续的叶片薄壁特征精铸收缩率计算与分布规律建模提供数据支持。
The blade middle section is adopted as the typical part to study the method for separating bending deformation, and a calculation method for deformation rectification is proposed. The displacement field which is separated, can be used as the data support for shrinkage calculation and deformation distribution modeling.
