基于Python的ABAQUS二次开发在骨钻削仿真中的应用

Secondary development of ABAQUS in the simulation of bone drilling based on Python

在骨外科手术中,骨钻孔占据了重要地位,而钻孔温度更是影响骨细胞坏死的重要因素。为了研究在钻孔过程中不同因素对温度的影响,基于ABAQUS有限元软件进行仿真,采用Python脚本语言对ABAQUS软件的前处理模块进行优化,修改钻削模型的Python脚本程序,创建了参数化的骨钻削模型。有效地简化了建立模型的繁琐过程,且建立了友好的人机界面,为用户仿真提供了便捷的分析设计平台。通过实验验证了该功能的可行性,为后续研究不同的钻削用量对钻削温度的影响奠定了基础。

In bone surgery, bone drilling occupied an important position, the drilling temperature is an important factor of affecting the bone cell necrosis. In order to study the effect of different factors on the drilling process temperature. Simulation based on the ABAQUS finite element software. The python language was used for pre-processing module of ABAQUS for optimization. Modify the python script of drilling model, create a parametric model of bone drilling, which effectively simplify the tedious process of model building and establish a friendly interface, provide users with a convenient platform for analysis and design. Verified the feasibility of the function by experiments and gave a way for further research on different drilling rates on the drilling temperature in bone drilling.
