摘要
通过理论分析、有限元仿真和实验验证的方式进行大底脚螺纹抽钉从1到0的反向应用基础研究,建立了安装过程中力的演变规律和平衡关系,得到安装性能(预紧力、鼓包直径和高度)与关键几何参数的匹配关系,开发了可实现自动建模和仿真计算的参数化求解模块.研究结果对提高大底脚螺纹抽钉的可靠性、经济效益,推动自主研发进程具有指导意义.
Abstract
Through theoretical analysis,finite element simulation,and experimental verification,the reverse research from 1 to 0 on basic applications of screw type blind rivets was studied.The evo-lution and equilibrium of forces during installation processes were established.The relationships of in-stallation performance(preload,diameter and height of blind head)and key geometric parameters were obtained.And a parametric module was developed,which might achieve automatic modeling and simulation calculations.The results have guiding significance for enhancing connection reliability,im-proving economic benefits,and for promoting the processes of independent research and development of the screw type blind rivets.
