借助光滑粒子流体动力学(SPH)方法,对所建立的低压铸造充型模型进行了数值模拟,并将模拟结果与Win-cast软件的模拟结果进行对比.结果表明,SPH方法与Win-cast软件模拟结果基本一致,能够较准确地模拟低压铸造充型过程.“,”The smoothed particle hydrodynamics method (SPH) was used to simulate the filling process of low pressure casting,and the simulated results were compared with those of Win-cast software.The results show that the SPH method is basically consistent with those of Win-cast software,so the SPH method can simulate the filling process of low pressure casting accurately.
