Abstract
A remote tension measurement system and method of use is provided for detection and estimation of tension in two-dimensional and three-dimensional inflatable structures. Given a spacing distance and a known mass of the membrane-formed structure, measurement points are determined to define a measurement region of the structure. A non-invasive sensor monitors the measurement points to detect a transverse wave moving along the measurement region at an angle to a straight path between measurement points. Propagation speed for the transverse wave is calculated and tension for the measurement region is deduced from the calculation. The solution exploits either proactively introduced, pre-existing, induced by normal environmental conditions) and/or multiple transverse vibrations in the membrane-formed structure. Propagation speed is calculated deterministically based on an analysis of the arrays of measurement points.
