摘要
针对中低速磁浮列车间隙传感器通过轨道缝隙时悬浮间隙值测量存在较大误差的问题,采用有限元分析的方法对间隙传感器内的检测线圈间距进行优化。利用ANSYS软件建立双线圈过40 mm轨道缝隙的三维仿真模型,对间隙传感器在不同线圈间距下进行垂向检测特性和额定悬浮间隙时横向过轨道缝隙的检测特性进行仿真。得到了不同线圈间距下的误差分布曲线,仿真结果表明:检测线圈间距为87 mm是满足误差要求的最小线圈间距,为最优的线圈间距。
Aiming at the problem that there is a large error in measurement of levitation gap value when the sensor of the medium-low speed maglev train passes through the track seam,finite element analysis method is introduced to optimize the space between two detection coils of the gap sensor.A three-dimensional simulation model of dualcoil with 40 mm track seam is established by ANSYS software.Vertical detection characteristics of the gap sensor under different space between coils are simulated,and the detection characteristics of the transverse over track seam with rated elevation gap are simulated too.The error distribution curves are obtained for different space between coils.The simulation results show that the space between coils of 87 mm is the minimum to meet the error requirement,and it is the optimal space between coils.
