为研究纤维铺放轨迹规划和优化算法,在分析等铺放角法和等距偏置法两种轨迹规划方法的基础上,提出基于纤维带边缘曲线的轨迹规划方法和纤维带丝束数量计算方法.在轨迹铺放角范围满足设计要求的前提下,将等铺放角法和等距偏置法两种轨迹规划方法相结合,提出以曲线在曲面内等距偏置为核心的铺放轨迹优化方法.该算法可以提高铺放设备的工作效率,并对纤维带丝束数量、纤维重叠面积、纤维间隙面积等铺放信息的计算方法进行了分析.最后将以上分析结果应用到S形进气道曲面的铺放轨迹规划中,证明了该铺放轨迹规划和优化方法的可行性.

In order to study the fiber placement path planning and optimization algorithm, based on equivalent placement angle method and isometric offset method analysis, the article proposed a placement path planning algorithm based on tape boundaries and tape tow number calculation method. A placement path calculating method, treating isometric offset of curves in the surface as its core idea, was proposed by combining the algorithms of isometric placement method and equivalent placement angle method in the scope of placement angle designed originally. The proposed algorithm can improve the efficiency of fiber placement equipment. Placement information was analyzed which mainly including tape tow number, tow overlap area, tow gap area, etc. Finally, by applying to the path planning of the S-shaped inlet the analysis results above, this paper proved that the feasibility of path planning and optimization algorithm.
