摘要
基于NX10.0平台,使用Block UI Styler块样式编辑器,设计前处理向导界面,完成后处理缺陷显示及溢流槽交互界面开发.利用二次开发工具,编写了NX中的切片法网格剖分程序;通过对模拟流动场文件遍历完成卷气缺陷查找,使用UFUN的面片相关API函数完成卷气和缩孔、缩松缺陷后处理显示,实现了压铸数值模拟系统集成.运用NX的表达式技术,创建了溢流槽的参数化模型及对应的表达式,通过缺陷重心的投影得到溢流槽定位,实现了溢流槽快速建模.通过罩壳压铸件的应用实例,表明本系统简化了模拟步骤,提高了产品开发效率,具有较大的实用价值.
Abstract
Block UI Styler block style editor was utilized to design the pre-processing wizard interface based on NX10.0 platform,and the development of post-processing defect display and overflow groove interface was completed.Using the secondary development tool,the program of NX mesh segmentation by slice method was written.The simu-lated flow field file was traversed to look up the enrolling defects,and the surface related API function of UFUN was adopted to complete the post-processing display of enrolling and porosity defects,achieving the numerical simulation system integration of die casting.The NX expression technique was applied to create a parametric model of overflow groove as well as corresponding expression.The overflow groove location was obtained by gravity center projection of defect,and the rapid modeling of overflow groove was realized.The application example of shell die casting indicates that the system simplifies the simulation steps,and improves the efficiency of product development,which is of practi-cal value.
