Аннотация: The purpose of this study is to develop a software and hardware complex for robotic defect detection systems, which will reduce the measurement time and reduce labor costs. The main method of detecting defects in this article is the registration of the effect of a change in the resonant frequency of oscillations of rail lashes due to the formation of defects. Simulation and evaluation of the effect of linear dimensions of defects for a regular cylinder and a sphere is given. It is shown that even defects with sizes up to 1 mm give frequency shifts for the first harmonic up to 10 Hz, and also data are given on the formation of additional oscillatory modes from the position of the defect relative to the edges of the rail lash. The second part of the article contains materials on the development of software and hardware for recording vibration data by a radar method.
