CHOICE OF A TRUCK SPRING SUSPENSION SYSTEM FOR HIGH-SPEED FREIGHT CARS

K VYBORU SISTEMY RESSORNOGO PODVESIVANIJA TELEZEK GRUZOVYH VAGONOV DLJA VYSOKIH SKOROSTEJ DVIZENIJA

Description of a method for the theoretical study of these systems, involving speeds of up to 140 km/h. The frequency-amplitude characteristics are analysed as well as the spectral density of vibration in wagons equipped with different suspension systems. The method proposed in this article recommends, for the construction of freight wagons intended for speeds ranging from 140 to 150 km/h, that use be made of a twin spring suspension with greatest possible static deflection (consistent with the conditions for automatic-coupler connection), and that this equipment should for the most part be housed above the axle-box. In this way, the bogie will be subjected to lesser acceleration.
