Simulation Prediction and Control Verification of Curing Deformation on Typical Composite Structure
针对典型复合材料结构固化成型过程中变形难以控制的问题,本文对典型复合材料结构的固化变形进行仿真预测,从固化工艺和模具补偿两方面对固化变形加以控制和验证.固化工艺方面以各设计点变形数据为基础确定了最优固化工艺曲线,模具补偿方面提出了一种构件有限元模型自适应调整的方法,综合考虑固化工艺参数与模具型面补偿采用了一种基于全局补偿量的协同控制方法.结果表明,通过仿真模拟L形构件的固化变形误差为12.4％,借助响应面优化算法得到的L形构件最优固化工艺曲线其固…查看全部>>
In response to the problem of difficult control of deformation during the curing process of typical composite material structures,the curing deformation of typical composite structures was simulated and predicted,and the curing deformation was controlled and verified from two aspects:curing process and die compensation.In terms of curing process,the optimal curing process curve was determined based on the deformation data of each design point.In terms of mol…查看全部>>
