Elevator vibration attenuation method and device

The invention discloses an elevator vibration attenuation method and device. The elevator vibration attenuation method comprises the steps that the current actual elevator car load and the current elevator floor position are obtained; a car load is selected from recorded car loads, wherein the difference between the selected car load and the actual elevator car load is within the preset range, and the selected car load is used as the current car load; according to the corresponding relation among recorded car loads, the elevator floor position and servo motor rotation displacement, the servo motor rotation displacement corresponding to the current car load and the current elevator floor position is determined; according to the determined rotation displacement, a servo motor installed on a guide shoe is adjusted. According to the elevator vibration attenuation method and device, the requirement for acceleration signal collection real-time performance and accuracy is lowered, the servo motor adjusting accuracy and the elevator riding comfort level are improved, and meanwhile the problem that the guide shoe is damaged caused by over adjustment of the servo motor is avoided due to the fact that the rotation displacement of the servo motor is a known and determined adjustment variable.
