[Objective]The pipe belt conveyors are crucial equipment for bulk material transportation with significant environmental advantages.This study is aimed to quantify the lateral bending stiffness of steel cord conveyor belts.[Methods]Based on the analysis of standard ISO 703:2017,the measurement and analysis method for the lateral bending stiffness was determined.Numerical model and 3D simulation model of the steel cord conveyor belt were established.Deformation data under different schemes was obtained using numerical analysis method and finite element method.Error analysis was conducted to demonstrate the validity of the models.Furthermore,a generalized deflection formula for the lateral bending stiffness was derived based on the functional dependence of the belt's troughability on elastic modulus,linear mass,and cross-sectional geometric parameters.[Results]The results provide a new perspective for quantifying the lateral bending stiffness of pipe conveyor belts and offer a basis for their design and engineering practice.
