Dynamic Characteristics of Multi-Rope Friction Hoists
Aiming at the problem of easy damage during the operation of multi-rope friction hoist,JKMD-5 x 4 multi-rope friction hoist is taken as the research object and its dynamic characteristics are analysed.Firstly,the basic situation of the hoist is briefly introduced,and the finite element model of the hoist spindle module is constructed,and then force analysis,harmonic response analysis,transient dynamics analysis and vibration characteristics analysis of the spindle are carried out respectively on this basis.Finally,according to the simulation results of the operating state of the hoist control,in order to verify the accuracy of the simulation results.Through the actual verification,it can be found that compared with the original control method,the optimised control method is more stable in the operation of the hoist,which significantly reduces the probability of hoist failure.
