Measurement of Resistance Force of Conveyor Belt Passing on Carrier Roller (Development of Substitutive Method with Self-traveling Roller)

Abstract

The purpose of this study is to reveal specific factors which determined the experimental results obtained by self-traveling roller for evaluating the property of indentation rolling resistance, comparing the data shown by conventional test system. In the novel test method with self-traveling roller, the cart which was the loading part of a carrier roller was dragged in the driving direction vertically pushing the flat conveyor belt between the roller and rigid and straight aluminum rail flame. In conventional test method with endless driven belt, Indentation load and indentation rolling resistance was measured by two load cells attached between bearing holder for carrier roller and the flame vertically and horizontally, respectively. The trace of indentation displacements were not symmetric, where time to recovery was longer than that to indent. The relationship between their experimental results obtained by the novel method in which self-traveling roller was applied was well agreed with that by conventional test method. Hysteresis loops were observed, when load-displacement curves was investigated under simple vertical indentation. The hysteresis loss energy was not depended on the clamping condition, while the increasing point of the curves was different. Novel test method with self-traveling roller had a potential as a substitutive test method to evaluate the indentation rolling resistance of the conveyer belt.
