Abstract:

Aimed at path generation for automatically fiber placement of sculptured surfaces,an algorithm called WEM  was proposed.A family of wraps as the reference lines were adaptively generated based on the surface shape. According to the process data of the fibers for composite tow, fiber placement path were obtained,which formed  fixed placement angle with the corresponding reference curve.This algorithm might be applied in the kind of free-form spline surface with parametric method description. The simulation shows that the algorithm is feasible and effective.

Key words: sculptured , surface;fiber placement;warp , envolopment method(WEM);composite

摘要:

针对复杂曲面自动铺丝轨迹生成问题,提出一种可自动生成铺丝轨迹的经线包络法,即按照曲面形态,自适应生成一族包络整个曲面的经线,然后以此作为参考线,根据复合材料铺丝束纤维的宽度、数量等工艺数据,生成与对应参考线成固定铺放角度的铺丝轨迹。该算法适用于采用参数方法描述的复杂曲面,仿真实例表明该算法可行且有效。
