【摘要】：以3D-Kagome点阵夹芯板为研究对象,采用Anycasting软件对A356合金点阵夹芯板的低压熔模铸造过程进行数值模拟,研究了浇注系统及主要的工艺参数对A356合金点阵夹芯板成形的影响,并在此基础上进行了工艺优化。结果表明,随着浇注温度提高,金属液的充型能力增加,缺陷减少,但当温度超过770℃时,缩松、缩孔缺陷有增加的趋势。通过模拟计算,确定了点阵夹芯板最佳浇注工艺:浇注温度为770℃,型壳预热温度为200℃,充型速度为40mm/s,并将模拟试验结果进行试验验证,表明该工艺切实可行。
[Abstract]:The low pressure investment casting process of A356 alloy lattice sandwich panel was numerically simulated by Anycasting software. The influence of pouring system and main process parameters on the forming of A356 alloy lattice sandwich plate was studied. On this basis, the process was optimized. The results show that with the increase of pouring temperature, the filling capacity of molten metal increases and the defects decrease, but when the temperature exceeds 770 鈩，
