英语翻译
To reduce the cost．it is necessary to identify the hard-to—cast wheels prior to the die manufacture and prototyping,so that castability issues can be explored early in the designing stage to avoid the manufacture of faulty and expensive dies．To take such advantages,the die casting industry has now adopted the computer based simulation technique which showed advantages over the conventional trial-and-error
methodologies for design and optimization[9-13] ．In this paper,the numerical simulation system ViewCast was used to simulate the temperature and velocity fields during the filling and solidification stages of LPDC aluminum alloy wheel．The
present work was aimed to predict the location and volume of defects,and modification has been applied to the original process in order to improve the quality of casting．

为了降低成本,它是要找准难以铸造车轮前的模具制造和原型,使铸性问题早在设计阶段可以探讨,以避免出现故障,昂贵的模具制造,采取这样的优势,压铸行业现在已经采用了基于计算机模拟的技术,它显示以上的常规试验和错误的优势
设计和优化的方法[9-13],本文的数值模拟系统ViewCast的被用来模拟在低压铸造铝合金轮毂的填充和凝固阶段的温度和速度场,
目前的工作,目的是预测缺陷的位置和数量,并修改已经应用到原工艺,以提高铸件质量.
