摘要 根据LCM工艺树脂流动充模模型和FEM/CV算法开发了LCM工艺计算机过程模拟的 3DLCM系统 ,考查了工字型孔尺寸或位置对平板构件充模过程的影响 ,并进行了对比实验 ,同时分析了其流动充模模式的变化规律。结果表明模拟结果与实验结果具有较好的吻合性。模拟软件可以比较准确地模拟LCM工艺的充模过程 ,为指导实际工艺的设计及优化奠定了重要的基础。 A 3D LCM (liquid composite molding) system of LCM processing simulation is developed based on resin flowing/filling model of LCM process and FEM/CV method to investigate the influence of Ⅰ-shape hole dimension/location o n filling time of 2D plane. Corresponding comparative experiment is perfor med and the filling mode change is also analyzed.It is indicated that experimental results m atch the simulation resul ts well. This software can correctly simulate the LCM filling process and provid e an important base of the actual process design and optimization.
