摘　　要：随着飞机设计制造领域的蓬勃发展,新机型对复合材料整体结构的刚度需求日益增加,飞机翼梁结构厚度也随之增大。大厚度的特点为零件的制造增加了难度。以一大厚度C型复合材料翼梁为研究对象,讨论了大厚度C型梁结构的研制难点,并对零件制造的关键控制点进行了分析实验。对制造工艺参数进行了迭代优化,并以此为基础成功研制了大厚度C型翼梁零件,研制的大尺寸大厚度复合材料C型梁内部质量、表面质量、厚度公差及外形公差能够很好地满足设计要求,具有较高的科学意义与工程应用价值。With the vigorous development of aircraft design and manufacturing,the new aircraft have an increasing demand for the stiffness of the composite overall structure,and the thickness of the aircraft bearing beam structure has also increased.The characteristics of large thickness increases the complexity of production processes.In this paper,taking a large thickness C-type composite bearing beam as the research object,the difficulties of the production process were discussed,and the key control points of part manufacturing were analyzed and experimented.Then,the manufacturing process parameters were iteratively optimized,and on this basis,the large-thickness C-shaped fender parts were successfully developed.The internal quality,surface finish,thickness tolerance,and dimensional tolerance of the manufactured large thickness C-type bearing beam meet the design requirements effectively,which has high scientific significance and engineering application value.
