摘　　要：提出一种五棱台式测量探头侧面倾角的优化方法,通过量化磁梯度张量各独立分量的相对分辨率与探头侧面倾角之间的关系,以5个独立分量相对分辨率的极差与最大值为评估标准,得出五棱台式探头的侧面最优倾斜角度。最后,通过仿真量化了棱台侧面倾角误差对测量结果的影响,为棱台的加工工艺明确了精度要求。This paper presents a optimization method of slanting surfaces of a five-sided pyramidal probe based on quantified relations between the relative resolution of each magnetic gradient tensor′s independent component and inclination of the probe.The optimal inclination was chosen on the basis of the range and maximum value of the five relative resolutions of the independent components.Finally,simulation results quantify the influence of surface tilt error on the measurement results,and identify the processing accuracy of the probe.
