【摘要】 针对ProCAST软件建模和网格划分能力不强的问题,讨论了前处理软件与ProCAST的3种接口方式。以模拟低压铸造铝合金轮毂的网格划分为例,编写数据转换程序,实现了Pro/E、ANSYS等前处理软件与ProCAST软件的联接,解决了复杂?精细铸件无法在MeshCAST中划分有限元网格的问题。分析比较网格划分的质量,结果表明,采用Pro/E建模划分网格,经数据转换程序导入ProCAST再进行模拟分析是最为有效、快捷的工作方式,可以显著提高铸造模拟计算的精度和速度。更多还原

【Abstract】 Aiming at modeling and meshing deficiency of Procast software, three interface modes of preprocess software and Procast software have been approached. Data exchange program is written to process the interface of Pro/E, ANSYS software and Procast software by meshing aluminum alloy wheel simulation grid in low pressure casting, effectively solving the meshment of finite element grid of complicate parts in Meshcast software. By comparing the modes of modeling and meshing, it is a most efficient way to conduct simulation by using Pro/E modeling and meshing grid, and then transmitting exchanging data into Procast software based on data exchanging program, improving the speed and accuracy of simulation calculation.更多还原
