FIELD: transport.
SUBSTANCE: device for dynamic testing the electric rolling stock current collectors is equipped with pneumatic rubber-cord components installed in parallel to resilient components. Chambers of pneumatic rubber-cord components are connected with compressed air sources via regulating valves. Herewith, in the rubber-cord components and at the corners of platform, pressure sensors and elevation sensors respectively are installed. These sensors are connected with electronic control system the outputs of which are connected with regulating valves using electropneumatic converters and pneumatic positioners.
EFFECT: higher accuracy of current collectors testing results.
