The Influence of High-Frequency Cyclic Loading on the Mechanical Properties of Steel
The modern development of high-speed transport causes a requirement toughening of the safety requirements for rolling stock and upper track components. Researchers and constructors are actively working towards the creation of more complete and adequate models of constructers and their elements, as well as new materials for their manufacture. The problem of studying traditional materials in various modes of rolling stock operation, including increasing the frequencies of dynamic influences and imposing effects from various loads and oscillations to the high-frequency area, becomes relevant and timely. This work is devoted to modeling the influence of high-frequency loading on a sample made of rail steel, this kind of influence takes place when rolling stock passes through an artificial constructer. It is assumed that the work of the rail within the sleepers step is described by the laws of uniaxial tension-compression. Experimental results and conclusions on ultrasonic high-frequency cyclic tests and structural analysis of the model material - low-carbon steel of the perlite class are presented.
