| 摘 要： | 在铸造生产的造型方法中,粘土砂湿型造型是涉及离散的材料体系、材料非线性、几何非线性、接触非线性等问题共存的一个复杂的力学过程,因此对造型过程进行数值模拟比较困难。采用有限元方法是求解非线性问题的的有效数值方法。采用ANSYS软件对湿砂造型中的压实造型过程进行数值模拟,取得了较好的结果。

| Abstract: | Although green sand squeeze molding is very popular in casting production, from the point of view of mechanics it is a complicated process which includes material nonlinearity, geometrical nonlinearity, and contact nonlinearity problems. All these cause difficuties in simulating the squeeze moulding process numerically. Nonlinear Finite Element Method is an effective numerical tool to solve these problems. In this paper a commercial software has been used to simulate the stress field of green sand moulding. Results show that the present approach is promissing. |
