Improvement of the methodique's for the experimental measurement of the systems of moving single-arms pantograph's rigidity electric locomotives

The article provides for the design features of pantographs of an electric drive train, a system of movable frames, which are made in the form of two articulated rod-type levers. Single-lever pantographs are distinguished by improved mass-dimensional indicators, which allows them to be used in the cramped conditions of the roof space of two-system electric locomotives. This requires high mechanical characteristics, as well as the need to use structural materials of increased strength, precision processing methods and high precision during assembly. It becomes especially important to control the transverse and advanced cruelty of the moving frame system during research, periodic and qualification tests, as well as during operation. The article describes a methodology that allows conducting research with a high degree of labor intensity, increasing the speed of measurements, and reducing the influence of the human factor.
