Abstract
We have developed an active roller guide system to suppress the lateral vibration of high-speed elevators. Lateral vibration is mainly caused by guide rail deformation and guide rail alignment error. We proved that the active roller guide system is theoretically better than other active vibration isolation methods from a point of electric consumption view. We have developed an original digital-filtering algorithm that enables to avoid waste of electric power due to low frequency noise of accelerometers. These optimum designs enable the development of low electricity consumption system. We manufactured an active roller guide and conducted experiments with actual elevators in experimental towers. Experimental results show that the active roller guide system is capable of reducing the lateral vibration of elevator cars to nearly half with low power consumption.
