面向主动再制造的航空发动机涡轮叶片需求分析研究

摘要

Aiming at the status of current production’s hard remanufacturing after product failure, directing by multi-life cycle theory, triple requirement elements for the green remanufacturing products is sum-marized, and the entropy method and AHP is combined with to deal with multiple requirements. On the basis of exploring the requirement conversion and conlfict resolu-tion, the requirements analyzing model for product active remanufacturing based on QFD and TRIZ is put forward. Finally, the above method is validated by an example of aircraft acro engine turbine blade to illustrate the proposed framework in the sustainable designing quality improve-ment role for the green manufacture product.%就产品失效后再制造难的问题，以多寿命周期理论为指导，归纳出面向产品绿色再制造的多重需求要素，并结合熵权法和AHP确定其权重；在探讨需求转换和冲突解决的基础上，形成基于QFD和TRIZ的面向主动再制造的产品需求分析模型。以某型航空发动机涡轮叶片的需求分析为例说明了此模型对产品绿色再制造的可持续设计质量的改进作用。
