摘　　要：根据复合材料的特点及其构件成形过程,总结复合材料铺层排样的特点,并拟定采用多边形排样算法实现复合材料自动排样的思路。重点研究简单多边形零件靠接时移动方向和移动距离的确定、多个可排放位置的状态评估、零件排放后多边形边界的合成等关键技术。利用模拟退火算法与以上多边形排放技术相结合,实现多边形零件的优化排放。According to the characteristic of composites and the special making procedure of its parts, the composite packing characteristics are summed up. Based on the characteristics, a polygon placement scheme is proposed to automatically nest composites pieces within the rectangular stock. Three key polygon packing technologies are studied,which include calculation of feasible sliding vector and sliding distance when one polygon slides along the other＇s boundary,evaluation of all the feasible positions,combination of the new placed polygons boundary with original one. Theses technologies are used to implement the placement of pieces with certain sequence, and the sequence can be optimized by simulated annealing （SA） algorithm.
