Electric current in the cable winding generates a traveling magnetic field which pulls the vehicle along without contact. The support magnets form the exciter (i. e. the motor).
通电螺线管里的电流产生里一个移动磁场，以非接触的方式驱动车辆。

At present, the law of the research on traveling wave effect for cable-stayed bridge with support system is rare in domestic.
目前，国内对于支承体系斜拉桥行波效应影响规律的研究成果并不多见。

Based on the basis of traveling wave energy absorption method, the formula of allow tension increment of anchorage cable under condition of the blast wave shock is derived.
