Abstract

,2020 ABSTRACT The interest in magnesium alloys has progressively increased in several industrial fields in recent years, and AZ31 has become an object of the study of lightweight development. Due to its low density and high specific strength, magnesium alloys represent a promising alternative to aluminum alloys and high strength steels, especially for applications in the automobile industry, being used in structural components to reduce weight and, consequently, improve performance fuel efficiency. In recent decades, several tests were conducted to evaluate the formability of AZ31 and showed its high dependency on the temperature range. The main objective of the present study is to propose a fuzzy model to predict the limit drawing ratio (LDR) of an AZ31 sheet by varying its thickness, temperature, and speed in wide ranges. In order to validate the proposed model, comparisons were made with 6 studies performed by other authors –an amount of 46 experimental tests–, showing a very good agreement between experimental results and fuzzy results. The model predicts the limit drawing ratio with an accuracy of 92.1%.

用模糊逻辑预测AZ31镁合金拉深极限拉深比

摘要近年来，在多个工业领域，人们对镁合金的兴趣逐渐增加，AZ31成为轻量化发展的研究对象。由于其低密度和高比强度，镁合金代表了铝合金和高强度钢的一个有前途的替代品，特别是在汽车工业中的应用，用于结构部件，以减轻重量，从而提高性能燃油效率。近几十年来，对AZ31的成形性进行了多次试验，结果表明AZ31的成形性与温度范围有很大的关系。本研究的主要目的是提出一个模糊模型来预测AZ31板材的极限拉伸比(LDR)，该模型可以在宽范围内改变其厚度、温度和速度。为了验证所提出的模型，与其他作者的6项研究(共46项实验测试)进行了比较，实验结果与模糊结果非常吻合。该模型预测极限拉深比的精度为92.1%。

期刊介绍： Ingeniare. Revista chilena de ingeniería is published periodically, is printed in three issues per volume annually, publishing original articles by professional and academic authors belonging to public or private organisations, from Chile and the rest of the world, with the purpose of disseminating their experiences in engineering science and technology in the areas of Electronics, Electricity, Computing and Information Sciences, Mechanical, Acoustic, Industrial and Engineering Teaching. The abbreviated title of the journal is Ingeniare. Rev. chil. ing. , which should be used in bibliographies, footnotes and bibliographical references and strips.
