摘要: 采用PAM-RTM软件,对帽型加筋壁板结构进行了树脂流道仿真与设计。过程中,分别对注射口和溢料口在蒙皮、筋条等典型区域的分布位置和数量,树脂重力及注射溢料开关顺序对壁板树脂渗透效果及注射时间的影响进行了分析对比。仿真结果表明:采用蒙皮边缘两端注射帽顶溢料、从零件边缘向中央区域依次关闭溢料口的流道设计,零件出现缺陷的概率最小。以此仿真结果为参考,开展了帽型筋条壁板VARI工装设计与制造,最终通过零件成型及质量检测验证了仿真分析结果的有效性。

Abstract: The VARI process simulation of panel with hat-shaped stringer is carried out by PAM-RTM software. During the simulation, effect of the distribution position and quantity of injection ports and vent ports in typical areas such as panel skins and stringers, gravity of resin and vent port close sequence were analyzed respectively. The simulation results show that the possibility of defect appearance tends to be the lowest, when flow channel is designed in following way: ① The injection ports are distributed at panel skin edge and the vent ports at top of stringer. ② The vent ports close sequentially from the edge of the panel to the central area. Through the simulation results which were verified by the panel manufacturing with VARI and quality inspection results, the optimal resin flow and tooling design was finally obtained.
