| 摘 要： | 采用有限元分析方法对金刚石钻头进行了应力分析，重点研究了有限元分析时的两大难点：一是有限单元的离散，二是外载荷的处理。给出了有限元计算模型和外载荷值，并对计算结果按ＶＯＮ．ＭＩＳＥＳ屈服准则进行了分析，找出了应力分布形式及最大应力值。所有理论分析方法和研究结果均可直接用于生产设计。

| Abstract: | A finite element analysis of stress to a diamond bit is conducted It is focused on two difficulties:one is how to discretize finite elements;the other is to handle the external load on the bit A model for finite element calculation and values of the external load is given The results are processed according to the yield criterion of VON MISES The stress distribution in the bit is determined and the maximum stress point is positioned The analysis method and results can be used in designing and manufacturing diamond bits |
