| 中文摘要 | 为了提高机器人辅助针穿刺精度,提出一种对软组织变形分析的准静态有限元法.该方法基于针受力下软组织变形机理,将软组织变形的连续动态过程分解成离散的准静态过程;采用重叠单元法在ANSYS中建立了软组织变形的二维和三维准静态有限元模型,并进行了仿真实验.最后通过实验结果验证了该方法的有效性和可行性.; A quasi-static finite element approach is presented to simulate soft tissue deformation during robot-assisted needle insertion with satisfactory precision. Based on the needle force analysis and soft tissue deformation attributes,the dynamic process of soft tissue deformation during needle insertion is decomposed into a set of discrete quasi-static stages. At each stage,we derive the two and three dimensional quasi-static finite element models by ANSYS software with superposed element method. Experimental results demonstrate the validity and the applicability of our method for soft tissue deformation.; 国家自然科学基金(50775119); 美国密西根大学联合研究项目(CMMI#0825795) |
