Assessment of Operating Characteristic of Equipment Access Hatch Lifting and Guiding Devices

Focusing on the dynamics characteristics of lifting and guiding devices of equipment access hatch during opening and closing process, this paper adopts ADAMS (Automatic Dynamic Analysis of Mechanical Systems) to analyze the displacement property, including different displacement of the sleeves and distortion of the guiding rails. The kinetic simulation results indicate that: under synchronous condition, the lifting and guiding devices will not be restricted. However, the maximal altitudinal difference should be controlled within 54mm under non-synchronous condition, otherwise the lifting and guiding devices will be restricted.
