真空电炉的电极上设有真空密封,其库仑摩擦力往往很大,在电极升降伺服系统中表现为死区特性,因此,输入伺服阀的电流必须大于该死区值后油缸才开始运动。如何确定这一死区的大小?我们在某钢
There is a vacuum seal on the electrode of the vacuum electric furnace, and its Coulomb friction is very large. It appears as a dead zone characteristic in the electrode lifting servo system. Therefore, the current input to the servo valve must be greater than the dead zone before the cylinder begins to move. How to determine the size of this dead zone? We are in a steel
