Abstract
The gray cast iron is used in many machine parts such as pulleys, since it has excellent vibration damping, wear resistance, and castability. Material evaluation of this cast iron is important for quality assurance of machine products. This research proposes a method to identify defective products mixed with good products. Currently, test methods such as Brinell hardness and tensile strength tests are commonly used to check the quality of cast irons. However, these methods are not suitable for inspecting all products in terms of time required. Therefore, it is important to establish an electromagnetic nondestructive test that enables non-contact and fast measurement. It has been found that the use of AC magnetic fields in nondestructive testing methods can be used to measure defective gray cast iron. In this paper, we propose an electromagnetic nondestructive testing method that uses a DC-biased sinusoidal magnetic field, which enables measurements with higher sensitivity than those obtained with AC magnetic fields. The effectiveness of the proposed method is demonstrated through electromagnetic field finite element method (FEM) analysis using the play model method and corroborated by verification experiments.
灰口铸铁具有优异的减震性、耐磨性和可铸性,因此被广泛应用于滑轮等机械零件中。对这种铸铁进行材料评估对于保证机械产品的质量非常重要。本研究提出了一种识别混入良品的次品的方法。目前,通常使用布氏硬度和拉伸强度测试等测试方法来检查铸铁的质量。然而,从所需时间来看,这些方法并不适合检测所有产品。因此,建立一种能够进行非接触式快速测量的电磁无损检测方法就显得尤为重要。研究发现,在无损检测方法中使用交流磁场可用于测量有缺陷的灰铸铁。在本文中,我们提出了一种使用直流偏压正弦磁场的电磁无损检测方法,这种方法比使用交流磁场的测量灵敏度更高。通过使用 play 模型法进行电磁场有限元法(FEM)分析,证明了所提方法的有效性,并通过验证实验予以证实。
期刊介绍:
The International Journal of Metalcasting is dedicated to leading the transfer of research and technology for the global metalcasting industry. The quarterly publication keeps the latest developments in metalcasting research and technology in front of the scientific leaders in our global industry throughout the year. All papers published in the the journal are approved after a rigorous peer review process. The editorial peer review board represents three international metalcasting groups: academia (metalcasting professors), science and research (personnel from national labs, research and scientific institutions), and industry (leading technical personnel from metalcasting facilities).
