基于UGNX的起重机锻造单钩参数化设计

Parametric Design of Crane Forging Single-hook Based on UGNX

依托UGNX系统建立锻造单钩的三维数字化模型,建立吊钩的主体尺寸之间及与截面尺寸之间的参数化关系,在此过程中通过UGNX的结构仿真模块中所带结构分析解算程序NX.Nastran和自带第三方解算程序Ansys对吊钩截面进行有限元分析优化,确保参数化设计的同时满足强度的要求。利用其加工模块对锻造单钩的锻模编制数控加工刀路,实现计算机数字化模拟加工,检查参数化设计后的吊钩制造工艺性是否合理,从而全面验证参数化设计的合理性及优越性。

A three-dimensional digital model of a forging single-hook was constructed based on UGNX system and the parametric relationship between the main size and section size of a hook were established. During this process, the structure analysis program NX. Nastran and the third-party solution procedure Ansys in the module of structure simulation analysis were used to optimize the finite element analysis on cross-section of the hook so as to ensure that the parametric design can meet the requirements of the intensity at the same time. The manufacturing module was used to construct NC tool path for the forging die of the forged single-hook, to realize computer digital simulation of manufacturing. The rationality of the manufacturing process of forged single-hook after parametric design was checked, which verified the rationality and superiority of parametric design comprehensively.
