Simulation Study on Dynamic Characteristic of Marine Elevator

摘要

Marine passenger elevator is as a new type of special equipment, which has been extensively used in all kinds of marine and marine engineering development equipment. The accelerations between the simulation and test of each working conditions is different, but the trend of change is basically consistent. The simulation results could serve as reference for marine elevator structure design. During simulation, the gap between the guide and boot is not taken into consideration, which may be the main cause of the difference. It is clearly seen that when the rolling cycle is constant. The angle of rolling is increased, whose value is obviously increased. The maximum possible acceleration under due to rolling is 1.665 m/s~2 under normal condition, and that due to pitching is reduced to 0.939 m/s~2. The maximum value caused by the combination of rolling and pitching is 1.596 m/s~2. The maximum value under abnormal working condition is 1.734 m/s~2, which is slightly more than that under normal working condition. The safety factor of the prototype is at least 1.7 times higher than that of the landed elevator.
