电子3D打印关键问题及其在无线电能传输中的应用研究

发布时间：2021-04-28 04:55

　　无线电能传输技术（Wireless Power Transfer,WPT）作为一种便捷、安全、高效的能量传输方式得到了企业和研究人员的广泛关注。现有无线电能传输系统采用的都是平面（2D）线圈,2D线圈可以直接集成在我们的手机、电脑、鼠标等有大平面的电子设备外壳上,但不能用于电动剃须刀、谷歌眼镜、植入式医疗设备等3D外形的电子产品。近期,电子3D打印技术的快速发展为无线电能传输系统的设计、制造提供了新的思路和方法。电子3D打印技术增加了无线电能传输系统中线圈设计及制造的维度,线圈的设计、制造不再局限于平面。针对目前无线电能传输中遇到的问题,并结合电子3D打印技术,作者在本文中:提出了一种自由曲面上3D线圈的标准化设计方法;构建了完整的用于计算3D线圈参数的数学模型;设计了一种提高斜面上导电轨迹打印质量的加工方法;最后,提出一种基于遗传算法的3D线圈的优化方法。本文的主要研究内容如下:（1）验证了3D打印线圈用于无线电能传输的可行性,并针对不规则自由曲面上3D线圈无法标准化设计的问题,提出了一种基于非均匀有理B样条曲线（Non-Uniform Rational B-Spline,NURBS...
