摘　　要：转辙机转换力的传统检测方法是采用人工巡查,其实效性不够,易造成设备故障。随着铁路的大提速,对设备质量提出了更高的要求,转辙机转换力必须进行实时监测,以便及时进行维护。通过在轨采集转辙机电气参数(电压、电流和功率),计算转辙机转换力,实现对道岔转换力的监测。研究结果表明,用测量电气参数去估算转辙机转换力的方法,在一定偏差内能真实地反映转换力的变化情况。The conventional approach to test the transfer force of point machine is manual inception,which is lack of effective and easy to cause equipment failure.Nowadays,the requirements for the quality of equipment become higher and higher due to the great speeded-up of trains.Therefore,the real-time monitoring for the transfer force of point machine has to be employed,so that the maintenance can be conducted in time.Through the satellite monitoring of electrical parameters（e.g.,voltage,current and power）,and the calculation of transfer force,the turnouts′ switching power can be monitored.As a result,the method of estimating the point machine′s transfer force by testing the electrical parameters can reflect the real situation of transfer force within certain deviation.
