Title:
METHOD AND DEVICE FOR PREVENTING IMPACT VIBRATION OF LIFT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/103048
Kind Code:
A1
Abstract:
A method and device for preventing impact vibration of a lift system, the method comprising: acquiring a load weight in a lift container (5); obtaining preset basic parameters of a lift system; according to the load weight in the lift container (5) and the basic parameters of the lift system, determining a fundamental wave vibration period of a lifting rope (4) when the lift system starts; according to the fundamental wave vibration period and preset calculation parameters of the lift system, determining time-varying simulation parameters of an acceleration of the lift system during a lifting process; according to determined time-varying simulation parameters of the acceleration, lifting the lift container (5).
