In the moveing process of hydraulic drive car,because the rapid moving car has large kinetic energy,the transport car and the positioning device would have a mechanical collision when the hydraulic cylinder pushes trolley to the terminal.In this paper,an electro-hydraulic servo system combined with ultrasonic detection is used to monitor the location of the transport car in real time and to apply buffer to the trolley travel terminal.On the one hand,it can realize deceleration operation of the hydraulic cylinder terminal stroke;on the other hand,it can ensure accurate movement of the car to th...
