航空发动机管路数字化制造及应用

Digital manufacturing and application of aero-engine pipeline

针对航空发动机管路先取样后生产传统制造模式存在的周期长、成本高的不足,建立了航空发动机管路数字化制造流程,实现了外部管路设计、制造和检验的全数字化数据传递。利用数据库技术,结合航空发动机管路实际制造需求,在制造企业现有资源和技术基础上,构建了导管数控折弯回弹补偿数据库,实现了导管折弯回弹的预测。以Teamcenter系统为平台,突破了柔性组合夹具数字化拼装关键技术。建立的管路数字化制造流程和方法成功应用于航空发动机管路实际制造,获得了良好的效果;管路一次装机合格率达到96%,制造周期缩短一半。

Aiming at the long-term and high-cost shortage of the traditional manufacturing mode for aero-engine pipelines,the digital manufacturing process of the aero-engine pipelines was established,and the all-digital data transmission of the external pipeline design,manufacture and inspection was realized.Using database technology,combined with the actual manufacturing requirements of aero-engine pipelines,based on the existing resources and technical support of the manufacturing enterprise,the NC bending springback compensation database was constructed to realize the prediction of pipeline bending springback.The Teamcenter system was used as a platform to sort out the key technology of digital assembly of flexible combined fixtures.The digital manufacturing method was applied to the actual manufacture of aero-engine pipelines.The application results show that the qualification rate of one installation is 96%and the manufacturing cycle can be shortened by half.
