摘要
本文进行了金刚石砂轮平面磨削超细硬质合金残余应力有限元仿真,通过ANSYS软件中的APDL参数设计语言,完成了对超细硬质合金材料建模、网格划分、加载、求解的整个过程,并对超细硬质合金磨削表面残余应力进行了实验论证,得出了不同磨削参数下的磨削残余应力值,对比了不同目数砂轮和不同WC晶粒硬质合金在同一磨削参数下的残余应力值。研究发现,目数小的砂轮磨削时产生的残余应力值要大,WC晶粒度越小,磨削的残余应力值越大。结果表明,实验结果与有限元模拟大致相同。
Finite elementsimulation onprecision grinding residual stress of diamond grinding wheel is presented for calculating when grinding Ultrafine cemented carbide .ANSYS parameter design language （APDL ） was applied to the whole process of modeling, meshing, loading and solving on Ultrafine cemented carbide material . Experiment of grinding residual stress was carried out , Residual stress of diamond grinding wheel was found on different grinding parameters. Both grinding wheel of different mesh number and Ultrafine cemented carbide of different Grain size were compared under the same grinding parameter. The study found：The grinding wheel of low mesh number result in High value of Residual Stress, small Grain size of cemented carbide led to high value of Residual Stress ,the result of Experiment is much similar to finite element simulation.
