До питання методів побудови систем захисту від надлишкового ковзання коліс рейкових транспортних засобів

Abstract

Контроль ковзання завжди був вирішальним у залізничному секторі через обмежене тертя між колесами та рейкою. У цьому дослідженні будуть розглянуті різні типи захисту від ковзання та ковзання для залізничних транспортних засобів. На основі чого будувати реалізацію максимальної сили тяги відповідно до умов зчеплення. Підвищення тягового зусилля є комплексною проблемою проєктування залізничних транспортних засобів; тому необхідно розробити ефективні системи тяги та алгоритми. Постійний розвиток інтелектуальних систем управління дозволяє будувати системи управління на основі сигналів зовнішнього середовища. Такі типи сигналів можуть бути отримані багатофункціональними датчиками, як камери.Various types of protection against skidding and the use of rail vehicles are considered, based on which the implementation of the maximum traction force under the coupling conditions is built. Slip control has always been crucial in the railway sector due to the limited friction between the wheels and the rail. This study will examine the various types of skid and skid protection for rail vehicles, on which basis the implementation of the maximum traction force in accordance with the clutch conditions will be build. Increasing the traction force is a complex problem in the design of railway vehicles; therefore, it is necessary to develop effective traction systems and algorithms. The continuous development of intelligent control systems allows building control systems based on signals from the external environment. These types of signals can be received by multifunctional sensors such as cameras. Wagons are constantly being improved to reduce time and safety. Therefore, they need a powerful traction control system to meet the increasing speed requirements. The development of a traction control strategy to achieve optimal traction ensures a safe and efficient ride and reduces unnecessary slippage between the wheel and the track. Therefore, the development of modern control systems that eliminate these problems is an urgent task. The issue of setting up an excessive slip and shake control system was specially studied from the point of view of energy efficiency in many sources. Optimal decommunization strategies were proposed to ensure a trade-off analysis between travel time and electricity costs. The results showed that this research topic was very promising and that intelligent control systems based on computer vision and machine learning must be integrated into one management system. The use of traditional sensors in railway transport traction drives (angular speed, current, voltage) makes it possible not only to detect skidding but also to generate a signal proportional to the speed of excess slip, which ensures the adjustment of the traction force under the condition of coupling. The experiment on measuring linear speed and calculating sliding speed was performed on an experimental bench. The use of modern computer vision technologies will make it possible to measure even small linear velocities up to 1 m/c with an error of no more than 2 %.
