摘　　要：经对差动变压器线性范围的理论分析,认为影响差动变压器线性范围的关键因素是:差动变压器轴向磁场的磁感应强度,而差动变压器轴向磁场的磁感应强度受初级线圈的长度和平均半径、衔铁的长度和半径、初级激励电压等因素影响。采用MATLAB对影响差动变压器轴向磁场的磁感应强度的各个因素进行了模拟设计计算,选定了优化参数并制作差动变压器。实验证明,优化后制作的差动变压器线性范围合乎设计要求,用MATLAB计算分析差动变压器线性范围的方法可行。Through theoritical analysis on the linear range of transducer of differential transformer,it is believed that the magnetic induction density of axial magnetic field is the key factor that affects the linear range of the transducer,while the magnetic induction density is affected by such factors as the length and average radius of both primary coil and armature,and primary exciting voltage.After simulating calculation,above parameters are optimally determined,and the differential transformer is made.The experiment shows that the linear range of the differential transformer made meets the demand of design,then the method to calculate the linear range with the use of MATLAB is feasible.
