Straightening technique for distorted aeronautical monolithic component based on finite element numerical simulation

  • 摘要: 针对航空整体结构件变形复杂、校正效果难以定量预测的工程问题,基于有限元仿真技术,综合研究加工变形—校正过程,对航空整体结构件的变形校正有限元建模、校正过程数值模拟、校正参数确定、校正载荷施加形式及校正残余应力等关键技术进行了研究,并运用上述技术对某航空铝合金材料整体结构件进行了变形校正有限元数值模拟.结果表明,综合研究加工变形—校正过程,提取变形有限元模型作为初始校正模型,进行有限元加载—卸载分析,可很好地模拟校正过程,并获得实际需要的校正参数.
