The　six　degrees　of　freedom　(6-DOF)　Stewart　platform　is　modeled　and　simulated　by　virtual　prototype　technology.　This　method　is　very　effective　to　avoid　the　difficult　in　solution　of　work　space,　which　may　cause　the　problem　of　interference　in　actuators　or　other　abnormal　case.　Besides,　it　can　reveal　the　movement　of　the　platform　obviously,　so　platform　motion　control　strategy　can　be　designed　efficiently.　It　can　ensure　that　the　real　platform　can　run　safely.　The　method　is　not　only　simple,　efficient　but　innovates　in　related　study.
