Abstract：Regarding thesynchronous position deviationcausedby hydraulic cylinders during the working processof lifting mechanisms forwheelloader，anoptimized synchronouscontrolsystemwas designed.Thebasic structureandcoreparametersof thelifting mechanismforwheelloaderswereelaborated，andamathematical modelofthelfting mechanismwas establishedand mechanical analysis was conducted. Schematic diagram of the hydraulicsystem of the lifting mechanism was drawn using FluidSIMsoftware，andsimulationanalysiswasconducted.Usingsensorsand electromagneticproportional directionalvalvesas hardware cores，a simulation model ofasynchronous control system withPIDcontrol link was constructed byAMESim，and simulationanalysis wasconducted.Theanalysisresultsindicate that the application of PID controlsystem improvesthe synchronizationaccuracyof the lifting mechanismof heavy-dutyvehicles，andmaintains thecontinuousandstableoperationof theliftingmechanism ofwheel loader.
