| 摘 要： | 压花机压制过程中压力很大,在使用过程中发现机架某些部位会产生裂纹.运用COSMOS仿真软件对该结构分析,从压花机运动仿真入手,得到有限元分析所需准确的边界条件与约束.在此基础上进行了压花机机架有限元分析.结果表明,其危险区域并非严格的对称分布,主要集中在边角处及螺纹孔处.经多次的改进、分析比较,最终确定出一种能节省材料又使最大应力减小的方案.

| Abstract: | There was rather big pressure during the pressing process of embossing machine,it has been discovered during the course of application that cracking would be engendered at some places of the frame.The COSMOS simulation software was used on the analysis of this structure.Proceed with the kinematic simulation of embossing machine,the accurate boundary condition and constraint needed by the finite element analysis were obtained,and onthis basis the finite element analysis of the frame of embossing machine was ... |
