摘　　要：根据复合材料力学和线弹性断裂力学 ,假设钻削轴向力为一集中作用载荷 ,从而构造了正交纤维束增强复合材料的钻削分层临界力的数学模型 ,仿真结果表明 ,随着待钻削深度的减小 ,分层临界力急剧降低。基于这一特点 ,提出了多元变参数振动钻削纤维增强复合材料的新思路 。Based on laminated plate theory and linear elastic fracture mechanics approach in which thrust force is assumed as a concentrated load, a mathematical model is established to predict critical thrust force of drilling delamination for cross-plied fiber reinforced composite material. Simulation results indicate that delamination critical thrust force decreases rapidly with reduction of the depth to be drilled. According to the characteristics, a brand new idea of multiple-varying parameter vibration drilling for composite materials is presented and verified by experiments.
