Development of an Axial Strain Measurement System for Rails

A kind of strain measurement system of electromagnetic railguns based on Bragg Grating technology was introduced in this paper. The Bragg grating strain measurement system of electromagnetic railguns was designed. The data processing and the calibration of the measurement system were discussed. The experiments of strain measurement in electromagnetic launch were accomplished. The results show that the Bragg grating strain measurement system can work reliably in strong electromagnetic interference, which satisfied the special demand of anti- electromagnetic interference for the strain measurement system.

Axial Tensile

The StressProbe is a non-contacting electromagnetic tool that responds to material strain in ferromagnetic materials. Previous studies have concentrated on uni-axial strain measurements; in this study, we extend the scope of work by measuring bi-axial strains on a pipe specimen subject to internal pressure and to a displacement-controlled, axial tensile/compressive load. Specified pressure and load combinations were obtained, and measurements from the StressProbe were compared to those from tri-axial strain gauges installed on the pipe specimen. In this paper, we present the theory behind this measurement method and the results from this study. Also discussed are measurement applications both inside and outside the pipe specimen.
