The　main　factors　that　affect　comfort　in　speed　elevators　are　horizontal　and　vertical　vibrations.　To　improve　comfort　and　mitigate　the　effects　of　vibration　and　shock　inside　elevator　equipment,　the　kinetic　parameters　of　the　elevator　vibrations　are　optimized.　The　process　of　running　the　speed　and　acceleration　of　the　high-speed　elevator　in　the　virtual　prototype　simulation　by　virtual　prototype　technology　(VPT)　technology　is　completed,　a　sensitivity　analysis　method　is　used,　and　the　kinetic　parameters　of　vibrations　that　affect　the　vertical　and　horizontal　directions　of　the　elevator　system　are　optimized.　The　simulation　results　show　that　the　vertical　vibration　acceleration　of　the　optimized　elevator　system　dropped　from　1.12　m/s2　to　1.04　m/s2,　and　the　horizontal　vibration　acceleration　of　the　lift　car　is　less　than　0.1　m/s2.　This　ensures　that　the　maximum　amplitude　of　the　vertical　and　horizontal　vibration　acceleration　is　reduced,　the　ride　comfort　of　the　elevator　is　improved,　and　an　effective　way　to　optimize　the　research　and　design　of　the　high-speed　elevator　system　is　provided.　©,　2015,　Nanjing　University　of　Aeronautics　an　Astronautics.　All　right　reserved.
