论文部分内容阅读
编辑同志你好!今天拜读贵刊2012年5期中第125页《拉板的销孔受力分析和应用计算》一文,感觉很好,打算推荐给我的同事和引入教材中。仔细审阅后发现结果分析有问题:表一和(1)中都说明B1的应力最大,而这一点的应力不可能比B2大,B1点的应力是拉应力和弯曲应力的差,B2点才是拉应力和弯曲应力的和,另外,我也利用有限元进行了校对。我认为该文章有待推敲,请予以关注。
Editor comrades Hello! Today, read your magazine in 2012 5 of 125 in the “pull the pin hole force analysis and application calculation,” a text, I feel very good, intends to recommend to my colleagues and the introduction of teaching materials. Careful review and found that there is a problem analysis: Table 1 and (1) shows that the maximum stress B1, and this stress can not be greater than B2, B1 stress is the difference between tensile stress and bending stress, B2 only Is the sum of tensile stress and bending stress, and I also proofread using finite element. I think the article is to be considered, please pay attention.
