生物瓣支架造型研究

Research on the Modeling of Biological Valves Poppet

以心瓣流体动力学理论、薄膜壳体理论为依据,导引出生物瓣支架的基本雏形并建立其数学模型。通过对与不同几何模型瓣架相贴合的瓣叶型面的有限元分析,使其几何模型构建的合理性得以证明。生物瓣支架计算机辅助设计是通过模块化结构的设计方法并对其进行参数化设计来实现。

In this paper are described the construction of biological valves poppet and the establishment of mathematical model according to cardiac valves hydrokinetics and the theory of membrane. Finite elements of biological valves leaflets connected with biological valves poppet are analyzed. The method of constructing geometric model is reasonable. CAD of biological valves poppet is realized by structured programming and parameterization.
