摘　　要：人工机械心脏瓣膜是自然心脏瓣膜的替代物,随着对人工心脏瓣膜血流动力学认识的深入,新材料的应用,人工机械心脏瓣膜计算机模拟、测试手段的提高,使得人工机械心脏瓣膜研究成为国内外新兴研究的热点之一。通过SolidWorks及其分析软件COSMOSWorks进行新型三叶瓣的研究开发,分析机械心脏瓣膜的结构组成及设计要求进行瓣叶与瓣环的结构设计。对瓣叶选择合适的网格化分,用COSMOSWorks软件自带求解器进行应力与应变分析。为进一步研制新型人工机械心脏瓣膜提供了一种参考方法。Artificially mechanical heart valve is the substitution of human heart valve. Artificially mechanical heart valve is researched into as a new hotspots studies at home and abroad, with the deeper learning of the hemodynamics of mechanical heart valve, applications of new material, and the method of the computer simulation and improvement of testing method. The Solidworks and COSMOSWorks software is not only used to assist the research job of a new trileaflet mechanical valve model, but also used to analyze the structure and design requirement of the trileaflet mechanical valve model. The own solver of COSMOSWorks software is the acceptable choice to mesh the valve leaflet. A advanced way is put forward to research new artificially mechanical hear valve.
