The shortage of loading in design of horse head is indicated by analysis.Based on the distribution disciplinarian of Oil film stress of the limited width axis-diameter and mechanical analysis method of wheel to rope
the reasonable mechanical model is set up
the load distribution function on the interface of wheel to rope is deduced.When two different distribution of load is loaded
the difference in design of the horse head and the related components is given.By FEA
the cosine distribution of load is more reasonable and more credibility in during of design.
