摘要
以心瓣流体动力学理论、薄膜壳体理论为依据,以接近或达到人体天然心瓣的性能为目的,对生物瓣支架几何造型进行理论分析,进而导引出生物瓣支架的基本雏形,并建立其数学模型。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的。最终通过体外疲劳试验,证明其性能优良。
The construction of the creature valve frame is analyzed. The preliminary modeling and the mathematical modeling are built according to cardiac valves of hydrokinetics and the theory of the membrane to enable creature valves to take the place of cardiac valves of human being. CAD of the creature valve frame is realized by structured programming and parametrization. Finally, the fatigue test verify that the performance of the creature valve frame is reliable.
