我们于1981年2月11日曾在广州北站27道南端进行了一次将减速顶安装在钢轨外侧的试验,目的是试验溜放车辆通过钢轨外侧减速顶时滑动油缸能否与踏面外边发生冲击辗压接触而达到吸能减速,同时对溜放车辆通过钢轨内侧和外侧的减速顶时的动能损失进行比较。 On February 11, 1981, we conducted an experiment to install a decelerating roof on the outer side of the rail at the south end of No.27 Guangzhou North Railway Station to test whether the sliding cylinder can impact with the outside of the tread when the derailing vehicle passed the decelerating roof outside the rail Rolling contact to achieve energy absorption deceleration, while sliding vehicles through the rail inside and outside the deceleration top when the kinetic energy loss compared.
