The swing vehicle,with its special structure,can move forward,backward and stationarily without electricity and motor. The principle of the swing vehicle forward is analyzed in detail from the point of view of dynamics. The experiment demonstrates trajectory of the swing vehicle.%摇摆车结构特殊,无需电力和马达即可实现前进、后退及原地不动等动作。从动力学角度对摇摆车前进的原理进行了详细分析,并通过实验演示了摇摆车的运动轨迹。
