Abstract: Forthedifficultyonspacecraftgroundsimulationofhighprecisionmicrogravity,averticalweightlessmovementmethodbasedonequivalentdynamicswasproposed.Theequivalentdynamicsanditsconditionswerebroughtforwardtoimplementhighprecisionverticalweightlessmovementsimulation. Then, thesimulatordesignrequirementsbasedontheproposedmethodwereanalyzed.Throughsimulationanalysisofthesimulationaccuracy,thepossibleproblemsofthedesignprinciplewerediscussed. Erroranalysisandsimulationcalculationresultsshowtheweightlessnesssimulationaccuracyisupto99%,whichcansatisfytherequirementsofthehighprecisionmicrogravitysimulationexperiment.
