中文摘要 | 本研究之目的在分析人工膝關節之三維有限元素接觸應力。透過光電式三次元掃 描系統所掃描到的人工膝關節股骨與脛骨表面幾何資料,以曲面方式來建立人工膝關節股骨 與脛骨部分的有限元素模型,並探討人工脛骨部分超高分子聚乙烯襯墊採用線性與非線性材 料性質所分析得到之接觸應力分布情形。利用本研究中之步驟及方法可自動且精確的建立人 工膝關節三維限元素模型,而這些模型可提供做為評估不同邊界條件及負載條件下人工植入 物之間的應力分布情形,分析之結果可提供人工膝關節生物力學之資訊並可供相關研究參考 。 |
英文摘要 | The purpose of this study is to perform three-dimensional finite element contact stress analysis of the artificial knee joint. The surface geometric data of the artificial femoral and tibial components were obtained from a three-dimensional digital scanning system. The triangular surface models and the finite element meshes for the artificial femoral and tibial components were generated by using a commercial finite element software-MARC. Contact stress distributions for the UHMWPE insert of the tibial component were investigated for both linear and nonlinear material properties. From the procedure used in this study, geometrically accurate finite element models for the artificial knee joint were created. These models can provide a means for evaluating the stress distributions of the complex implant structure under various loading conditions. The results can provide valuable information for the design and analysis of the artificial knee joint. |
