摘　　要：利用ABAQUS软件建立各向异性皮质骨仿真模型,采用骨钻削的实验参数进行仿真,对照验证了材料属性设置为各向异性时的有限元模型能够较好地模拟骨钻削过程。利用该各向异性模型探究了钻削角度、进给速度和钻速对钻削温度、轴向力和扭矩的影响规律,通过响应面法构建了温度、轴向力与扭矩关于钻削参数的预报模型。该研究成果更符合骨裂固定手术的实际情境,为智能化骨骼钻削控制系统的开发奠定了基础。The anisotropic cortical bone simulation model is established by ABAQUS,and the bone drilling experimental parameters in the study are used to carry out the simulation experiment.It is verified by comparison that the finite element model with the material property set as anisotropic could simulate the bone drilling process better.The anisotropic model is used to investigate the effects of drilling angle,feed rate and drilling rate on drilling temperature,axial force and torque.The prediction model of drilling parameters including temperature,axial force and torque is established by response surface method.The research results of this paper are more in line with the actual situation of bone fracture fixation surgery and lay a foundation for the development of intelligent bone drilling control system.
