Improving the method of controlling the stress-strain state of steel structures of electromechanical systems

[摘要] The article presents the results of improving the method of controlling the stress-strain state of steel structures of mine hoisting machines, which can be attributed to electromechanical systems. The method of controlling the stress-strain state of steel structures of electromechanical systems subjected to fatigue failure is based on the use of mechanical properties of an optical fiber (OF) and the effect of photoelasticity arising from its deformation. The optical fiber is used as a sensor and allows to controlthe stress-strain state of metal structures in real time.
