摘要

设计中的过度规格或超额余量可以增强其吸收变化和不确定性的能力,但也会降低重量和成本等性能标准。本文展示了余量值法如何与CAE工具(如FEA)一起应用,以量化设计过于复杂而无法进行代数分析的多余余量。通过对法兰耦合设计的案例研究,说明了MVM的新应用环境,其中在MVM中使用拓扑优化来确定设计改进的机会。

CALCULATING TARGET THRESHOLDS FOR THE MARGIN VALUE METHOD USING COMPUTATIONAL TOOLS
Abstract Overspecification or excess margin in a design can enhance its ability to absorb changes and uncertainty, but also deteriorates performance criteria such as weight and cost. This paper shows how the Margin Value Method (article in review) can be applied in conjunction with CAE tools such as FEA to quantify excess margin where a design is too complex for algebraic analysis. This new application context for the MVM is illustrated using a case study of a flange coupling design, in which topology optimisation is used within the MVM to identify opportunities for design improvement.
