摘要/Abstract

摘要： 自动铺丝是一种先进的复合材料自动制造技术，广泛应用于制造形面复杂的复合材料构件。大曲率区域丝束的压实质量较差、铺放路径的方向偏差和转弯半径难以同时满足等问题，导致了各种铺放缺陷。研究了曲面曲率对路径性能的影响，建立了分区域路径规划机制。采用压辊到曲面的距离来表征丝束压实情况，并根据曲面曲率估算可压实丝束的数量。建立了局部方向偏差和转弯半径计算方法，并在路径密化过程中实时评价，在路径性能超出约束时进行分区。考虑了丝束压实、方向偏差及转弯半径对铺放路径的约束，保证了整张曲面的铺放质量和铺放效率。在翼梢小翼曲面上完成了路径规划方法的仿真和实验验证，结果表明：所提方法能够在复杂曲面上获得满足性能要求的铺放路径。

Abstract: Automated fiber placement is an advanced automatic manufacturing technology for composite materials, which is widely used in manufacturing composite components with complex shapes. However, the compaction quality of the fiber in the area of large curvature is poor. In addition, it is difficult to satisfy the directional deviation and the turning radius of the placement path at the same time, resulting in various placement defects. In this paper, the influence of surface curvature on path performance is studied and a new path planning method for complex surfaces with area partition is established. The distance between roller and the mold surface is used to estimate the fiber compaction quality and the fiber number placed simultaneously can be calculated by the surface curvature. The local direction deviation and steering radius are evaluated during the path generation process, and a new sector is partitioned when the evaluation results are out of constraints. The method fully considers the influence of compaction quality, direction deviation and turning radius on paving path, so that the placement quality and efficiency of the entire curved surface can be ensured. Simulations and experiments are completed on the winglet surface to verify the path planning method, and the results show that, by the proposed method, satisfactory component placement quality can be obtained on complex surface.

Key words: complex surfaces, automated fiber placement, path planning, sector partition, performance constraints
