摘要:

采用ANSYS仿真分析了深地钻具径向轴承在温度、载荷协同作用下的应力/应变分布状态。仿真结果表明,最大等效应力/应变出现在硬质合金/焊料界面(焊接界面)和硬质合金/硬质合金界面(摩擦界面)附近;温度显著提升应力/应变水平,300 ℃下的最大等效应力/应变较100 ℃下的最大等效应力/应变增大约2.5倍;轴承两端的摩擦应力高于中间区域,且更易发生黏着磨损。上述仿真结果与实地服役轴承的损伤分布特征高度吻合,可为径向轴承的优化设计提供理论参考。

Abstract:

The stress and strain distributions of radial bearings for deep drilling tools under the synergistic effects of temperature and load are studied via finite element simulations using ANSYS Workbench. The simulation results show that the maximum equivalent stress and strain occur near the cemented carbide-solder interface (i.e., the welding interface) and the cemented carbide-cemented carbide interface (i.e., the sliding interface). Temperature significantly increases the stress and strain levels; the maximum equivalent stress and strain at 300 ℃ are approximately 2.5 times higher than those at 100 ℃. The frictional stress at both ends of the bearings is higher than that in the middle region, making the end regions more susceptible to adhesive wear. The simulation results are in good agreement with the damage distribution characteristics observed after field application, indicating that these findings can provide a theoretical reference for the optimal design of radial bearings.
