摘要
引入并行计算方法在集群系统上实现对RTM成型过程的数值模拟,并编写了并行数值模拟软件,模拟二维薄壁构件的RTM工艺的注模过程,得到任意时刻的树脂流动前锋曲线、压力场分布,计算结果与其他研究成果吻合良好.算例结果表明,并行数值模拟方法有效提高了计算效率.
A novel method which used the parallel algorithm to simulate the process of mold-filling in RTM was proposed. Based on this method we programmed a parallel numerical software to simulate the process of mold-filling in RTM for a 2D shape thin parts and predict the resin flow front advancement and the distribution of pressure field at any instant in time. And good agreement is found between the results and other investigations. Numerical examples show that parallel numerical algorithm can reduce the calculation time and improve the calculation efficiency.
