摘要: 本文提出了一种对于含缺陷高聚物材料在加载过程中形成微弱热致磁场进行三维测量的传感器系统。简要介绍了传感器的主要技术参数,提高传感器测量灵敏度的技术措施以及背景磁场的处理方法;给出了该三维磁场测量传感器数据采集系统的硬件结构和软件流程。采用该传感器系统实验获得了聚合物PVC板材在恒定拉伸速率下微弱热致磁场变化规律的三维分量曲线图。 A sensor system suit for three-dimensional pyromagnetic field detecting is presented. That weak magnetic field concomitantly occurs with deformation heat on loading procedure of prefabricated defects polymer materials. The main technical parameters of sensors and the technical measures to improve sensor sensitivities are briefly introduced, including the treatment method for background magnetic field. The hardware structure and the software flow of data acquisition system for this three-dimensional pyromagnetic field detecting are provided. As an applied result, a sort of 3D component curves of weak magnetic field variation are obtained, which come from a PVC plate specimen under a constant tensile displacement load.
