A APDL program is developed for analyzing the contact stress of journal bearing pair of roller cone bit. The 25 contact stress cases of different clearance fit(including clearance of large bearing is bigger, equal to and smaller than that of small bearing) journal bearing pair of the 8 1/2XXX roller cone bit are analyzed. The result is that the maximum contact stress is less when the clearance of large journal bearing pair is smaller than or equal to that of small journal bearing pair.

该联系动作可以将联系信息添加到地址簿，可以发起通信会话，和/或可以将联系项放置到存储器空间中，以由在其中呈现该内容的应用之外的应用进行后续使用。

The results show that, for the elasto-plastic contact of tip-substrate approach and separation process, the material plastic yielding in the atomic level is still governed by the von Mises criterion. For the adhesion of flat-ended wedges, continuum mechanics can be still applied down to a few lattice constants within the contact region, and give reasonable results, apart from the discrepancies near the contact edges. Moreover, adhesion hysteresis occurs during unloading due to the atomic steps, where the unloading curve does not coincide with the loading one. This in turn supports the presumption proposed by Pollock for the adhesion of stepped spheres.

本文首先对针尖—基体模型的弹塑性接触机理进行了深入研究，指出在原子水平上材料的塑性屈服仍由Von Mises准则控制；对平底锥冲头粘着接触的模拟表明，除了在接触区边缘附近有一定差别外，接触力学方法在接触区内几个晶格常数范围内仍能给出令人满意的结果；由于原子台阶效应，加载与卸载曲线不重合，出现粘着滞后，证实了Pollock关于具有纳米阶梯结构的球体粘着滞后现象的推测。
