| Abstract: | Powered platform vehicle for transportation is the main equipment for transporting hull blocks between procedures in shipyard. This paper introduces the hydraulic system of powered platform vehicle, analyzes the operation principle of the hydraulic servo system of the constant power regulation based on DA control valve and the variable motor controlled by the proportional directional valve, and expatiates on a regulation control when a vehicle runs on different method to solve the problems of driving speed road surface and differential speed control. |
