Abstract

In this study, we obtain overwind buffer distance by using the Lagrange equation to establish the two-degrees-of-freedom mathematical model with vertical shaft lifting system in rolling process. Design of a buffer device which is composed of a hydraulic energy absorption and strip plastic deformation energy absorbing and analyze its working principle with mechanical and hydraulic system. Analysis of the overwind buffer time and buffer distance with loaded full overwind and no-load speed by using ADAMS and AMESim to build mechanical hydraulic combined simulation model of hydraulic steel-belt overwind buffer device. The simulation results show that: buffer time is 0.67 sec and buffer distance is 0.38 m with loaded full overwind; buffer time is 0.523 sec and buffer distance is 0.05 m with no-load speed overwind. The design of Hydraulic steel-belt overwind buffer device conforms with the requirements of safety regulation in coal mine.
