摘要
机翼翼梁是飞机的主承力构件,为了保证其成型质量和生产效率,需要采用自动化成型方式进行翼梁构件的生产制造。本文对目前翼梁成型方法的应用及研究现状进行了介绍,根据大尺寸变截面翼梁(长度大于10 m)的结构特点,研究了复合材料翼梁的自动铺丝成型技术。以M.TORRES龙门铺丝机为铺放平台,提出了翼梁的自动铺丝成型要点,确定了各个角度铺层的轨迹规划方法,结合轨迹规划情况,给出了翼梁的铺丝成型轨迹完善处理方案。最后,通过大尺寸复合材料翼梁的自动铺丝成型制造,验证了轨迹规划方法和轨迹处理方案的可行性与正确性,为国内自动铺丝技术在大尺寸复合材料翼梁成型上的应用提供参考。
Spar is the main load-bearing component of the aircraft.In order to ensure its forming quality and production efficiency,it is necessary to adopt an automated forming method to manufacture the spar component.In this paper,the application and research status of the spar forming methods are introduced.According to the structural characteristics of large-size gradual section spar(>10 m long),the automatic fiber placement technology of composite spar is studied.Then,with the gantry-type automated fiber placement machine of M.TORRES as the laying platform,the key points of automatic fiber placement in spar are put forward.Furthermore,the trajectory planning method of the layup at different angles is determined.Combined with the trajectory planning,the optimization scheme of fiber placement for spar is proposed.Finally,the feasibility and correctness of the trajectory planning algorithm and the optimization scheme are verified by the manufacturing of the full-size composite spar using the automatic fiber placement,which provides a reference for the application of the automatic fiber placement technology in the forming of the large-size composite spar in China.
