Quantitative Analysis of Influenced Factors against Flat Belt Behavior

Flat belts are mechanical elements used in various equipment systems such as conveyors and industrial machinery. In systems employing flat belts, stabilizing the belt behavior on the pulleys is a critical challenge, and extensive research has been conducted to understand the underlying principles. While belt behavior measurements and analytical predictions are known to agree well in idealized test environments with controlled conditions for principle verification, quantitative evaluation of behavior using analytical models has been difficult in large-scale real systems due to deviations from ideal conditions. If the behavior of flat belts at real system scales could be quantitatively evaluated, it would be applicable to standard flat belt system design and could lead to more efficient behavior adjustment during assembly and preliminary evaluation in new system design. Therefore, in this paper, with the aim of quantitatively evaluating flat belt behavior on pulleys at real system scale, we designed an experimental system capable of evaluating flat belt behavior on pulleys at real system scale and conducted experimental testing. Furthermore, we performed simulation analysis using an analytical model of the same size as the experimental system, compared the results with experimental data, and present the results of quantitative analysis of the discrepancies observed between experiments and simulations.
