    Determination of the Dynamic Characteristics of Freight Wagons with Various Bogie
    (Taylor & Francis, 2015) Myamlin, Serhiy V.; Lingaitis, Leonas P.; Dailydka, Stasys; Vaičiūnas, Gediminas; Bogdevičius, Marijonas; Bureika, Gintautas
    EN: In most cases, dynamic characteristics determine the wagon maintenance cycle, traffic safety, reliability and durability performance. The main dynamic indicators include the vertical Kvd and horizontal Khd dynamic coefficients as well as the stability coefficient Ks, which determines the wheel flange resistance to derailment. The article compares dynamic indications for three different types of bogies. There were no tangible differences observed for all the three different types of bogies running at a speed of 40 to 120 km/h on a direct tangent rail section. Nevertheless, there is a realistic potential to improve the dynamic indicators of a freight wagon by rationalising suspension unit parameters.

    Nestacionarieji ir Kvazistatiniai Gelezinkelio Traukiniгu Judejimo Rezimai
    (Vilniaus Gedimino Technicos Universitetas leidykla Technika, Vilnius, 2015) Blochinas, Eugenijus; Dailydka, Stasys; Lingaitis, Leonas P.; Ursuliak, Liudmyla V.
    LT: Monografija "Nestacionarieji ir kvazistatiniai gelezinkelio traukiniu judejimo rezimai" skirta skaitytojui, besidominciam traukinyje, kaip netiesineje daugiamaseje mechanineje sistemoje, vykstanciais procesais. Sie vyksta traukiniui pajudant is vietos, stabdant, keiciant traukos jega, judant kalnuoto profilio keliu. Knygoje aprasomos uzduotys sprendziamos taikant traukiniu judejimo pereinamuju arba nestacionariuju procesu teorija. Tam sukurta speciali programine iranga, pagrista monografijos autoriu sukurta traukiniu judejimo pereinamuju rezimu teorija. Knyga sudaryta taip, kad skaitytojas pradzioje susipazintu su traukiniu sastatu schemomis ir matematiniais modeliais traukinio judejimui modeliuoti. Taip pat aprasoma informacines sistemas "Traukinio dinamikos analizatorius" elementu tarpusavio sasaja. Autoriai monografija rekomenduoja gelezinkeliu traukos klausimus nuodugniau nagrinejantiems doktorantams ir pazengusiems magistrantams.
