多机多点牵引道岔同步性研究

多点牵引且使用外锁闭的大号码道岔的同步转换要求各牵引点转辙机、外锁闭与道岔尖轨充分协调运动，因此，我们根据道岔各牵引点开口准确地计算相应转辙机动程、外锁闭空动程等相关数据，同时改变转辙机起动顺序，作到六点牵引道岔尖轨基本同步运动。

Study on Synchronization of Switch with Many Points and Many Machines

By many points and using external locking devices,the synchronous switch of large-size switches needs harmony movement among each point machine,external locking devices and switches tongue,so according to the hatch of each switch s point,the corresponding data about stroke of the point machine and the stroke of external locking devices without load is exactly calculated,at the same time the startup sequence of the point machine changes to make sure six points drive the switches tongue in basic synchronization movement.
