Analysis and Estimation of Errors in Measuring the Tension of Aluminum Oxide Fibers on an Experimental Stand

Resumo

This article examines aspects of analyzing and estimating the systematic error in measuring the tension of alumina fibers on a tension tester with stationary fiber guides. The measurements are made during the rewinding and twisting of the fibers on an experimental stand. Calculations are performed to determine the components of the systematic error for the given testers. Among these components are the constant error and the periodic error, which in turn depend on the conditions of motion of the fibers in the tester’s guides, the fibers’ geometric characteristics, and the changes in the friction coefficient in relation to fiber velocity.
