Railway Design - a.y. 2016/2017


CFU: 9

Period (Year/Semester): I/II

Languade: Italian

Required/expected prior knowledge: Nothing

Lecturers: Pucillo Giovanni Pio  

Course objectives:
The aim of the course is to provide the basic knowledge on the railway techniques currently in use to solve the problems concerning the Mechanics, with a particular emphases on those regarding the Machine Design and the Mechanical Design, that arise during the design stage and during service of both infrastructure and rolling stock structural components.

Tables of contents: 
Railway System: generality; traditional and special railways; rolling stock; railway rigging. – Rolling stock classification: towed vehicles; locomotives; railcars. – Connection and rolling members: hooks; bumpers; command and signals; wheelsets (wheels, axles, rims); wheel-rail contact; special running gears; bushings; axle guards. – Brakes: brake steering; empty-load; continuous controller; compressed air, vacuum, direct, automatic, and unfailing control systems; braked weight. – Suspensions: functions; materials; flexibility and frequency; constant level. – Bogies: functions; primary and secondary suspensions; body/bogie connection; relative motions. – Railways lines: classification; horizontal and vertical alignment trend; rail and fastening systems; track and ballast; gauge; transition lead curves and vertical transitions; turnouts. – European Standard for Interoperability. – Resistance verification of the main rolling stock and superstructure components: application examples. – Rolling stock homologation tests. – Railway rigging members prequalification tests. – Thermal buckling of the continuous welded rail track. – Applications.

Education method:
