心脏辨膜相当于心脏的阀门,在心脏的泵血循环中起着极其重要的作用。但是由于辩膜炎症或瓣膜先天发育畸形,会导致辩膜狭窄或辩膜关闭不全等各种心脏瓣膜疾病,瓣膜的病变会使心脏超负荷工作,严重时导致心脏功能衰竭,危及生命。对于辫膜病变严重的患者,进行瓣膜置换手术是唯一有效的手段。三叶机械辩膜是一种人工瓣膜,因其较好的耐久性受到各国学者的关注。本文使用TRIZ进行三叶辨结构设计,在此基础上在Solid Works Flow Simulation中建立瓣膜流体分析数学模型,对模型进行定常流血流动力学分析,同时使用Solid Works Simulation对辨膜进行了模拟极限工作状态下的有限元分析。 相似文献

Abstract: Innovation is a process of taking an original idea and converting it into a business value, in which the engineers face some inventive problems which can be solved hardly by experience. TRIZ, as a new theory for companies in China, provides both conceptual and procedural knowledge for finding and solving inventive problems. Because the government plays a leading role in the diffusion of TRIZ, too many companies from different industries are waiting to be trained, but the quantity of the trainers mastering TRIZ is incompatible with that requirement. In this context, to improve the training effect, an interactive training model of TRIZ for the mechanical engineers in China is developed and the implementation in the form of training classes is carried out. The training process is divided into 6 phases as follows: selecting engineers, training stage-l, finding problems, training stage-2, finding solutions and summing up. The government, TRIZ institutions and companies to join the programs interact during the process. The government initiates and monitors a project in form of a training class of TRIZ and selects companies to join the programs. Each selected companies choose a few engineers to join the class and supervises the training result. The TRIZ institutions design the training courses and carry out training curriculum. With the beginning of the class, an effective communication channel is established by means of interview, discussion face to face, E-mail, QQ and so on. After two years training practices, the results show that innovative abilities of the engineers to join and pass the final examinations increased distinctly, and most of companies joined the training class have taken congnizance of the power of TRIZ for product innovation. This research proposes an interactive training model of TRIZ for mechanical engineers in China to expedite the knowledge diffusion of TRIZ. 相似文献
