摘要
介绍了铸件的结构和技术要求,利用数值模拟软件及自主开发的应用程序,模拟了铸件的充型过程和凝固过程,找出铸件动不平衡现象的原因,最后通过增加0.4～0.8 mm的工艺补正量,使动不平衡现象得以解决,铸件尺寸达到稳定,动平衡通过率超过99.5%,实现了飞轮铸件在垂直分型线上的生产。
The configuration and technical requirements of the casting were introduced. By using numeral simulation software and the self-developed application program, the mold filling process and solidification process were simulated, the reason that the casting had been dynamic： unbalancing was found out and by adding molding allowance of 04-0.8 mm, the problem of dynamic unbalance has been solved, the casting dimensions have been kept stable, the pass rate of dynamic： balance has been higher than 99.5% and so that it was realized to produce the flywheel on the vertical-parting molding line.
