当一般列车以高速转弯,车体及车内的物件和乘客都会受到离心力的作用。这是因为列车本来在直线前进,与转弯中车辆的前进方向不一致,于是产生了离心加速度。因此,很多列车在转弯时都需减速,摆式列车能够在普通路轨上的弯曲路段高速驶过而无需减速。摆式列车供乘客乘座的车体在转弯时可以侧向摆动。在电脑的控制下,当车辆向左转时,车体通过装有摇枕的倾摆机构向左倾摆,让重力抵消向右推的离心力。
When the general train turns at a high speed, the objects and passengers inside the car body and the car will be subjected to the centrifugal force. This is because the train was originally in a straight line, and the turning direction of the vehicle is inconsistent, then the centrifugal acceleration. As a result, many trains need to slow down while cornering, and tilting trains can pass at high speeds on curved sections of normal tracks without slowing down. Tilting trains Passengers ride on the body can turn sideways swinging. Under the control of the computer, when the vehicle turns to the left, the vehicle body tilts leftward through a tilting mechanism with a bolster, so that the gravity counteracts the centrifugal force pushed to the right.
