Abstract：Aiming at different dynamic characteristics of passenger elevator in different number of passenger，support seat system of 2.5 m/s high-speed-elevator was studied through the numerical simulation technique. Using mode superposition method in ANSYS finite element software，after the analysis of nature frequency for support seat system，the performance of dynamic was computed which the analysis was in three operating condition of elevator car，respectively，full-load，half-load and no-load，the relationship between external excitation frequency and dynamic performance was built，and the influence law of dynamic response was offered as the load changed. The results indicate that transverse displacement responses are obvious for the three I-beams of support seat system，and dynamic responses are basically identical. As the passengers increas in the car，the degree of the dynamic response of the I-beams is increased. Under the three usual operating conditions，the most degree of dynamic response is happened which external excitation frequency are beyond the first step natural frequency. The study of dynamic characteristics provides a theoretical basis for engineers to design a reasonable constructor of support seat system.
