摘要

本注释扩展了作者先前对惠特利阀建模的工作，通过使用六个相交和连续的椭圆来获得惠特利阀的广义数学表示：这提供了许多可用于获得最佳设计的自由参数。由于最优性是多目标的，许多目标相互冲突，我们关注恒定力场施加在阀门上的应力。选择了三种截然不同的设计，并对应力进行了分析，得出了结论，并对结果进行了讨论。

A Generalized mathematical representation of the shape of the Wheatley heart valve and the associated static stress fields upon opening and closing

This note extends previous work of the authors modelling the Wheatley valve by using six intersecting and contiguous ellipses to obtain a generalized mathematical representation of the Wheatley valve: this provides a number of free parameters that could be employed to obtain an optimal design. Since optimality is multi-objective with many of the objectives conflicting we focus on the stresses imposed on the valve by a constant force field. Three distinctly different designs are chosen and an analysis of the stresses is undertaken, conclusions are drawn and results are discussed.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
