MODERNIZATION OF THE CRATE SUSPENSION UNIT OF THE VL-80S ELECTRIC CARRIER

The article presents the development of a modernized design of a cradle suspension unit for an electric locomotive VL-80s with improved elastic-dissipative suspension properties with substantiation of dynamic and strength parameters. Numerical studies were carried out in the MathCAD 15 programming environment. For railway company is necessary to develop a new method of modernizing the cradle suspension of the VL-80s electric locomotive during overhaul repairs in order to improve the dynamic characteristics and increase the strength and reliability

Radiative π⁰ photoproduction on protons in the Δ⁺ (1232) region

The reaction γp → pπ<sup> </sup>0γ<sup>′</sup> has been measured with the Crystal Ball/TAPS detectors using the energy-tagged photon beam at the electron accelerator facility MAMI-B. Energy and angular differential cross-sections for the emitted photon γ<sup>′</sup> and angular differential cross-sections for the π<sup>0</sup> have been determined with high statistics in the energy range of the Δ<sup>+</sup> (1232)-resonance. Cross-sections and the ratio of the cross-section to the nonradiative process γp → pπ <sup>0</sup> are compared to theoretical reaction models, having the anomalous magnetic moment <i>κ<sub> Δ</sub></i> as free parameter. As the shape of the experimental distributions is not reproduced in detail by the model calculations, currently no extraction of <i>κ<sub> Δ</sub></i> is feasible
