航空发动机叶片自适应修复目标曲面重构
|
摘要
航空发动机叶片修复往往先采用激光熔覆,然后精密铣削。叶片变形和破损可能造成熔覆材料不足或铣削结果超差。为了给叶身熔覆和铣削提供足够的余量和满足设计要求的目标加工曲面,提出镜像模型驱动的叶身自适应修复曲面重构方法。以叶身设计曲面作为理论模型,以实际待修复叶身的测量值作为实作模型,引入叶身形状公差约束和叶身变形对熔覆和铣削加工的约束,建立了保证叶身曲面设计要求的目标曲面优化模型,并基于镜像模型优化处理熔覆阶段与铣削阶段的目标曲面。通过实例验证了所提优化模型的有效性和必要性。
Cost could be reduced with blade repairing.Laser cladding is used to add material on to-be-repaired blade.Defect or deformation maybe occurs on the used blade.To provide enough allowance for laser cladding and to find a machining surface covered by fused surface for milling,an adaptive repairing surface reconstruction method driven by images model was proposed,which took the design surface as the theory model and the practical measured value as the implementation model.The form tolerance and deformation of blade were introduced into machining surface optimization model to establish the objective surface optimization model for ensuring tolerance requirements.The effectiveness and necessity of proposed optimization model was proved by an application.
