摘要
基于轨道电路链型电路等效模型提出了一种新的轨道电路计算方法——有限元准对角线矩阵法，给出了其计算公式。采用该计算方法对城市轨道交通数字编码式音频轨道电路进行了仿真计算。
This paper presents a new type computing method of track circuit based on its equivalent link typed circuit model—the semi diagonal matrix method of finife elements,and provides its computing formulas.Using this method ,the paper processes the emulation calculation of digital coded audio frequency track circuit utilized in Urban Mass Transit ATC System, and analyzes the main factors effecting on the receiving voltage.
