Stretch elastic modulus and bend elastic modulus

摘要

PPROBLEM TO BE SOLVED: To provide a method for evaluating the buckling capacity of conveyor belts and capable of evaluation consistent having actual buckling capacity of the conveyor belts. PSOLUTION: In the buckling capacity evaluation method, a test sample of a tension member part, formed by layering a plurality of tension member layers 2 via coating rubber layers 3, is used to acquire a tensile modulus of elasticity and a bending elastic modulus. Material characteristic values of a characteristic value analysis model 7 of a conveyor belt are set, on the basis of the acquired tensile modulus of elasticity and the bending elastic modulus. The buckling capacity of the conveyor belt is evaluated, on the basis of a characteristic value Ev, the ratio between a critical buckling load of the conveyor belt computed by finite element analysis through the use of the characteristic value analysis model 7 and a reactive force generated when the conveyor belt is bent.
