某铸件螺孔缺陷的一种分析计算方法

An analysis and calculation method of screw hole defect for some casting

关重铸件螺孔内出现缩松缺陷后,根据螺孔装配受力要求,通过计算分析缺陷对螺孔受力的影响,提出快捷经济适用的处理方案,经过验证处理方案有效可行,为后续处理螺孔缺陷提供参考。

After the shrinkage defects appear in the screw holes of castings,according to the screw hole assembly force requirements,the effect of the defects on the screw hole force has been calculated and analyzed,while a quick and economical solution has been proposed.The solution is verified to be effective and feasible,which provides reference for follow-up treatment of screw hole defects.
