Abstract: The vibration is the main force affecting elevator comfort. In order to study the dynamic
characteristics of the 4.0 m/s ultra-high-speed elevator system, the lift cabin-car frame-guide rail-wire
rope coupled system was taken as the study object. First, the vibration dynamic model of vertical
system was built. Then, combined with automatic dynamic analysis of mechanical systems virtual
prototyping technology, the elevator virtual prototype model was built by establishing ropes dynamics
model, adding a contact force between the guide rail and the guide shoe, adding horizontal vibration
excitation and vertical vibration excitation. Dynamic characteristic simulation was carried out for this
model under setting certain constraints and drivers. The results showed that those performance
indicators such as vertical vibration acceleration and horizontal vibration acceleration were meeting
the requirements and the simulation results also provided design basis for the development of
ultra-high-speed elevators.

Key words: virtual prototype, ultra-high-speed elevator, vibration acceleration, dynamic simulation
