Description
Summary:碩士 === 國立臺灣大學 === 機械工程學研究所 === 99 === Due to the significant achievement of curing coronary narrowing, stents are widely applied to the other wounded parts of human body or specific medical purposes. Therefore, stents have got abundant developing potential. Stents’ conventional development process is: traditional design, manufacture of processing, performance testing, and FDA certification. Because traditional design method takes much time and can not efficiently do the modification according to the test results, to improve the efficiency of stent development, this research puts parametric design and finite element method into the development process so that the stents’ development process now changes as follows: parametric design, finite element simulation analysis, manufacture of processing, performance testing, and FDA certification. Finite element analysis is used to predict the results of performance testing. And the local design parameters of parametric design stents can be quickly modified according to the test result by finite element analysis. The cooperating between parametric design and finite element method significantly increases the efficiency of stent development and reduces its costs as well. In chapter 5 of this thesis, the local parameters of parametric design stent have been fine -tuned, through finite element analysis, the test of performance changes has been done, and the graph shows the corresponding relationship between various design parameters and stent performance. All of these have once again proven that parametric design and finite element method are important for stent development process.
