摘要

采用UG软件对低压铸造增压器壳体铸造模具进行三维造型

同时对模型进行简化。用Hypermesh软件对模型进行网格划分以获得高质量的网格

运用Abaqus软件模拟增压器壳体的铸造成形过程

对壳体模具在铸造过程中的变形进行分析

预测飞边产生的位置及大小

并与实际生产中产生的飞边作对比;采集模拟的分型面间隙数据

将间隙量补偿在模具上

对模具进行修正补偿

并进行铸造试验

铸件没有飞边

得到与预期相符的结果。

Abstract

3D molding for turbocharger shell was carried out by UG software and it was simplified at the same time.The Hypermesh software was employed to enmesh the model to get high quality mesh.The casting process of the turbocharger shell was simulated by Abaqus software to analyze deformation of shell mold during the casting process

and to predict the location and size of fin

which was compared with the actual production.Through collecting gap data of parting face in simulation

the mold was modified by compensating the gap date on mold

eliminating successfully fin defect on the turbocharge shell

which was verified by practical product.
