Descrizione del progetto
Nuovi metodi per rodiggi sostenibili
Nonostante svolga un ruolo centrale nel settore ferroviario, il rodiggio è soggetto a modifiche limitate. Si suggerisce che le innovazioni abbiano un doppio impatto aumentando il prezzo iniziale del rodiggio e riducendo al contempo i costi di manutenzione nonché, di conseguenza, i costi del ciclo di vita (LCC, life cycle cost). Tuttavia, rimane difficile misurare i risparmi a lungo termine. Il progetto NEXTGEAR, finanziato dall’UE, svilupperà un modello di costo universale che semplifica la stima dell’impatto economico di una proposta di innovazione e se e in che modo possono essere influenzati i costi iniziali e di manutenzione. Proporrà idee basate su nuovi materiali e metodi di produzione che riducono il peso del carrello. Il progetto studierà anche la costruzione di nuove sale montate ferroviarie economiche.
Obiettivo
The rail sector has recently seen only limited changes in running gear.The rail sector has recently seen only limited changes in running gear. A reason is that innovations have the tendency to increase the first cost of the running gear while they reduce the LCC by reduce maintenance costs. The long-term cost reduction, however, is not easy to quantify.
This dilemma will be addressed in WP1 where an updated Universal Cost Model based on the one from the Roll2Rail project will be developed that makes it possible to judge the economic impact of the innovation suggested for an operator using the vehicle. How can the costs for buying, operating and maintaining the vehicle be influenced?
Lower bogie weight would reduce wheel-rail forces and allow for higher payload. In WP2, the project is going to suggest ideas that are based both on the use of new materials and new manufacturing methods. Simulation techniques will be explored to allow optimisation of designs. It will be investigated whether required properties of the running gear such as stiffness and damping could be distributed through the structure rather than requiring specific components. In parallel, active control strategies will be investigated to improve the level of ride comfort or reduce wheel and rail damage.
The wheelset is another extremely important and safety-critical component in a rail vehicle. Since it represents a so-called “unsuspended mass” there is a desire to minimize the wheelset weight. The main objective of WP3 is a feasibility study on the use of composite materials for the construction of railway wheelsets. Technology concepts for a lightweight wheelset will be defined. Main focus areas are material selection, durability, manufacturing process and joining methods.
The output of this project will be important input for the parallel member project in IP1 both regarding the Cost Model and the technical innovations. There will also be a contribution to the overall S2R KPI’s and partly IP3.
