Abstract

The invention discloses a modeling method of an aerial work platform base plate automatic levelling system. The method includes the following steps: analyzing and simulating the ground according to work conditions of an aerial work platform bottom plate; invoking various hydraulic components from a hydraulic component design (HCD) library of AMESim according to a hydraulic system schematic diagram, and constructing a hydraulic system model; according to operating characteristics of the base plate, invoking a step signal, a switch signal and proportional-integral-derivative (PID) control from asignal library of AMESim, using a pressure value of each support leg as input to a assign a value to a function signal, outputting the function signal to an electromagnetic valve to form a closed-loop control system, and evaluating and optimizing the levelling precision of the base plate so as to complete construction of a control model. The modeling method of the aerial work platform base plateautomatic levelling system improves the leveling precision and response speed of the hydraulic system, and reduces the modeling complexity.
