【摘要】 通过测量钢轨周围的磁场可以间接测量钢轨中的电流大小,进而判断钢轨的工作状态是否正常。本文将使用ANSYS软件对钢轨电流产生的磁场进行仿真,找出钢轨周围磁场强度最大的位置,同时使用不同尺寸的极靴对磁场进行增强,并通过仿真分析对比增强的效果,确定了最佳的磁场增强方案。更多还原

【Abstract】 By measuring the magnetic field around the rail,we can know the current intensity in the rail indirectly,and then determine whether there is a fault.This paper presents the simulation results on the magnetic field generated by rail current,finds the location of maximum magnetic field intensity around the rail.At the same time we use different sizes of silicon steel plates to enhance the magnetic field,and contrast the effect of enhancement,determine the best solution of enhancement.更多还原
