摘要：
In order to optimize the liquid forming process of the complex perform structure, the resin flow during composite liquid molding process was simulated base on the finite element method/life and death node method. The molding process of the typical rectangle plate, circle plate structure and I rib reinforced panel was simulated and verified. The results show that the simulation results of molding process for typical rectangle plate and circle plate structure are in good agreement with the theoretical solutions, which verify the validation of the life and death node method in the resin flow front tracking. The molding process simulation of the non-uniform thickness cylinder with cavity and the cube three-dimensional entity structure verify the applicability of finite element method for the three-dimensional structure. The simulation method of liquid molding process base on the finite element method/life and death node method is more adaptive to the complex solution region, which can be used to predict the resin flow law of liquid molding process for the complex entity structure, guide the design and process optimization of the mould. © 2016, BUAA Culture Media Group Ltd.
