| Abstract: | According to the working curves of executive mechanism of aerial work platform,the matching methods for the hydraulic systems were presented,which included the revolution mechanism,the amplitude mechanism,the middle-arm mechanism,the up-arm mechanism and leveling system.The changing conditions of speed,acceleration and displacement for each sub-system of executive mechanism under closed-loop control were analyzed.The changing conditions of the system dynamic characters were explained under PID control and open-loop control. |
