Abstract
Abstract The paper analyzes static tests of pipe conveyors using various statistical indicators and points out the mutual interactions between individual roller stands. Individual measurements were performed on a physical model of a pipe conveyor, while the methodology and procedure were verified by experiments. 15 repetitions of the given series of measurements were selected, which was a compromise between time demands and statistical requirement. Normal contact forces on the individual rollers of three hexagonal roller stands acting on the conveyor belt for different tension forces in the static state (conveyor belt without movement and without transported material) were evaluated. The LabVIEW Signal Express 2010 program from the National Instruments Company was used to record the measured data. The measurements were evaluated by Microsoft Office Excel.
