Melnichuk V. Increase of safe speed of freight cars by rigging devices stabilizing of run

Dissertation is devoted providing of firmness of motion at a speed of 100?120 km/h of freight carriages of track 1520 mm on all of duration them life cycle (subject to the condition high-quality technical maintenance and repair). It is retuned that existent limitations of speed of train and mobile work to 70?80 km/h are related to the size of stalling speed of carriages on the light carts of fashion 18-100 (with "absorber wedge type Khanin"), exceeding of which makes a threat safety of motion and, as a rule, ends with an emergency stair from rails. The signs of loss of firmness of motion freight carriages are certain, dependence of stalling speed on wear surfaces of workings parts, to the state of work-load of carriage and plan of track. It is retimed that to damping of wagging of parts of light carts of fashion 18-100 "еxtra" hinder structural degree of freedom and wear out uncompensated wedge absorber. Influence of the indicated factors succeeded to be removed during modernization of carriages on the project S.03.04 (with elements "A. Staki" is instruction of ЦВ-0083). The analysis of unconcern of realization of structural speed is conducted by the carriages of new generation on the light carts of fashions 18-7020, 18-579 and other. The alternative method of increase of stalling speed of carriages of existent park is developed by their repair on technology "DNEPR" for possibility them subsequent safe exploitation with speed to 100 km/h (a category of "s" is after classification of UIC).
