残余应力是材料的基本属性之一,与零件的几何/尺寸稳定性和疲劳寿命直接相关。针对具有高精度要求的大型零件,其残余应力场的准确测量和预测一直是一个挑战。目前的残余应力场测量技术分为基于应变的有损法以及效率和精度较低的无损法。本文提出了一种基于变形力推断残余应力场的无损法。本方法通过能够反映去除材料后不平衡残余应力场整体效应的变形力来推断零件的残余应力场。利用虚功原理建立了变形力与残余应力场之间的力学关系,并引入正则化方法求解残余应力场。为验证方法的有效性,本文进行了理论验证和实际实验验证。实验结果表明,该方法对于大型结构件的残余应力场测量具有可靠的精度和灵活性。在数字化和智能制造的趋势下,该方法的基本原理为利用加工监测数据预测和补偿由残余应力引起的零件加工变形提供了重要参考。

The application of electrified railway directly promotes relevant studies on pantograph-catenary interaction. With the increase of train running speed, the operating conditions for pantograph and catenary have become increasingly complex. This paper reviews the related achievements contributed by groups and institutions around the world. This article specifically focuses on three aspects: The dynamic characteristics of the pantograph and catenary components, the systems’ dynamic properties, and the environmental influences on the pantograph-catenary interaction. In accordance with the existing studies, future research may prioritize the task of identifying the mechanism of contact force variation. This kind of study can be carried out by simplifying the pantograph-catenary interaction into a moving load problem and utilizing the theory of matching mechanical impedance. In addition, developing a computational platform that accommodates environmental interferences and multi-field coupling effects is necessary in order to further explore applications based on fundamental studies.

随着智能电网和能源互联网的发展,大规模实时电压/电场监测成为电力系统的迫切需求,这依赖于先进传感器件的大规模布置。电场测量在电力系统中具有重要意义。一方面,基于电场测量的电压反演可以实现高电压的非接触式测量,替代传统高压互感器,从而减少测量设备绝缘成本和安装难度;另一方面,电场测量还可以被应用于设备故障诊断、雷电预警、电磁环境测量等应用场景。传统的电场测量设备,如场磨等,往往体积大、成本高,无法大规模灵活布置。本文提出了一种静电力驱动的压阻式微型电场传感器。传感器被设计为四悬臂结构,悬臂在静电力的驱动下产生位移和应变,通过压阻材料转化为可测信
号。所提出的传感器具有尺寸小、成本低、功耗低、易于批量生产的优点。同时,该传感器还具有高信噪比、高分辨率及宽电场测量范围的特点。实验结果表明,所提出的传感器具有1.1~1100.0 kV·m−1的线性测量范围、112 V·m−1·Hz−1/2的交流电场分辨率以及496 Hz的截止频率。这一微型电场传感器将在智能电网及能源互联网中具有广泛的应用价值。
