Abstract：[Objective]To optimize the design parameters of cable belt conveyors and reduce operational resistance,a novel analytical model for the rolling resistance of guide pulleys on cables was proposed.[Methods]Firstly,the mechanism of rolling resistance generation was analyzed.Considering the elastic hysteresis characteristics of polymeric materials,nonlinear elastic forces and catenary-type influence factors were defined,and a calculation formula for the normal composite restoring force of guide pulleys was constructed.Secondly,based on the viscoelastic rolling model,the contact area between the guide pulley and the cable was simplified into two parts:the loading region from the contact center to the initial contact point and the unloading region from the contact center to the separation point.Finally,the distributed pressures within the corresponding loading and unloading regions were integrated and summed to derive an analytical model for the rolling resistance moment of guide pulleys on cables.[Results]Validation through an actual project shows a relative error of 4.14%between the theoretical calculated power and the actual value,and the trend of rolling resistance aligns with the inclined plane method for polymer rolling friction tests,confirming the model's validity.By integrating metaheuristic algorithms with regression analysis,a method is provided to globally account for the influence of multiple design variables,facilitating the optimal design of cable belt conveyors.
