中文摘要： 柔性多层材料是一种常见加工材料，在纺织制造、航天航空制造等行业有广泛应用，但由于其刚性差、加工过程工件容易产生较大的拉伸或挤压变形，这使得加工控制变得比较困难。本项目研究柔性多层材料加工变形动态补偿预测建模方法，以柔性多层材料加载变形分析为切入点，研究加工变形影响因素的提取；引入系统工程权重理论，创新性研究柔性多层材料加工变形影响因素权重评价方法，着重解决加工变形应如何补偿，路径规划，重叠、次要影响因素如何约简问题；探索性研究带测量反馈的、能表征加工变形影响因素与补偿量之间多输入-多输出的映射关系模型，解决加工变形补偿定量计算问题，形成完善的刀具补偿路径规划机制；最后设计实现加工变形补偿预测模型的嵌入式系统，开展加工实例验证、测试实验。本研究不仅将柔性多层材料加工变形分析推向数字化模拟仿真的深入研究阶段，同时为实现柔性多层材料一次性装夹、自动化加工提供有效理论和技术支撑。
