The article analyzes the main malfunctions of cars that occur during operation on the North-Western Railways. Faulty wheelset treads were identified as one of the major problems in the early stages of car repairs. An overview of modern methods for measuring surfaces using laser technology is presented. The article discusses the principles of operation of laser profilometers, their main components, as well as methods for processing the obtained data. The application of laser profilometers in various fields such as industry, construction, medicine and science are described. The advantages and disadvantages of laser profilometers compared to other surface measurement methods are also discussed. To reduce the stopping time of passing trains, it is proposed to introduce laser profilers on the railway tracks. As a template is applied to a real wheel for measurements during the technical inspection of a rolling stock car, so in the proposed method, measurements are made at points according to the template. The technical result is an increase in the accuracy of measurements by minimizing the human factor, global digitalization of technological processes and automation of rolling stock control along the route. In the course of the work, data obtained from measurements of various profiles of the surfaces of freight cars, including wheelsets, were analyzed in comparison with reference profiles.Show Abstract
