Abstract
The paper considers the main stages of development of a computer model of current collectors of an electric rolling stock. The original description of the kinematic scheme of a universal measuring current collector with the subsequent implementation of mathematical model in Matlab SimMechanics environment is offered. The model is based on the use of the method of homogeneous coordinates to represent the kinematic scheme of the current collector. It is shown that the computer model accurately and adequately describes the processes occurring with the current collector, is a universal instrument for simulating any types of current collectors, allows changing a wide range of parameters and characteristics incorporated in it.
Highlights
On the railways of the whole world, test trips using the latest methods of research and analysis of the current collection process are regularly carried out to assess the state of the contact suspensions and the process of their interaction with the current collectors of the electric rolling stock
For test trips intended to determine the quality of current collection, a universal diagnostic tool with the capability to implement the characteristics of known prospective current collectors of electric rolling stock is necessary [1]
When designing and developing a universal measuring current collector of electric rolling stock, it is important to choose the original model of a current collector, because the adjustment ranges, configuration and selection of parameters of the generated measuring current collector will depend on the original characteristics designed in the project
Summary
On the railways of the whole world, test trips using the latest methods of research and analysis of the current collection process are regularly carried out to assess the state of the contact suspensions and the process of their interaction with the current collectors of the electric rolling stock. The use of a special rolling stock for the testing of current collector devices is an economically costly measure, especially when using high-speed electric trains. The production of a measuring current collector of an electric rolling stock requires a considerable amount of time and money. For test trips intended to determine the quality of current collection, a universal diagnostic tool with the capability to implement the characteristics of known prospective current collectors of electric rolling stock is necessary [1]
