摘　　要：针对AC8A铝合金活塞在铸造过程中产生的铸造缺陷,采用AnyCasting模拟软件研究了保温冒口形状和尺寸及浇注系统对汽车活塞顶部和裙部缺陷形成的影响。结果表明,通过对横浇道的尺寸优化和冒口尺寸的优化,减少了活塞顶部和裙部的缩孔和缩松缺陷,提高了铸件合格率。To eliminate the casting defects in aluminum alloy piston during casting process, effects of the shape and size of the insulation riser as well as gating systems on the defect formation at the top and the skirt of the piston were investigated by the AnyCasting software. The results indicate that the shrinkage cavities are reduced through size optimization of runner and riser, thus enhancing qualified rates.
