Abstract


In the paper are presented the design stages, technical programming specifications, architecture, and project of a data acquisition software application - measurement, control, processing, representation, storage, and integration with the user interface, dedicated to the demonstrative experimental system (DES) for the functionality and effectiveness testing of a new method of reducing the vertical vibration of the railway vehicle car body. The DES comprises the experimental scale model of the car body (ESMC), supported on elastic rubber elements, and the measurement and control chain that integrates several specialized components for acquisition of experimental data and generation of control signals, controlled with the dedicated software application. The software application is to be realized in the Matlab programming environment, which includes specialized functions for connecting to different data acquisition systems.
