摘要/Abstract

摘要： 根据自动铺丝对于铺放轨迹的要求分析了轨迹规划过程中的影响因素。将网格化曲面的方法运用到主应力法中,充分发挥网格化法便于计算的优势。基于铺层设计所得的离散点的铺放角度信息来生成铺丝轨迹。提出了自左向右遍历型面求轨迹的算法且重点讨论了轨迹规划起始点的选取及边界处铺放轨迹的求取方法。引入重合度以对纤维的重合和离缝程度加以控制,使得预浸料能够按要求铺满型面。在基于VC++开发的轨迹规划软件上对算法进行验证,证明了该算法的可行性。

Abstract: Placement path planning is one of the key technologies of automated fiber placement, because its reasonability can mean the difference between success and failure to get a high-quality composite product. So reasonable placement path is the prerequisite of composite material processing. According to the requirements of automated fiber placement against placement path, factors affecting path planning are analyzed. To fully exploit its advantage of making calculation convenient, meshed surface method is applied to principal stress method. The placement paths are generated based on placement angle information of discrete points obtained from layer design. An algorithm that traverse the surface from left to right is proposed and the way to select the planning start-point and obtain the placement paths next to the borderline is also discussed. Overlap ratio is introduced to control the extent of fiber overlapping and separating and make prepreg placed on the surface as required . Its feasibility has been verified on path planning software based on VC++.

Key words: fiber placement, meshed surface, principal stress method, traversal method, coverage analysis
