USING additive manufacturing TO ACHIEVE 40% WEIGHT REDUCTION IN railway structures
To reduce the energy consumption of trains and rail wear, railway vehicles need to be made lighter.
The ARCCAM (Advanced RailCar Conception for Additive Manufacturing) project aims to reduce the weight of heavy components (undercarriage and bogie) by at least 40%.
The weight of the structures has been optimised using topological optimisation and re-design processes, while ensuring that all features remain in compliance with allowable criteria. Topological optimisation coupled with additive manufacturing makes it possible to reach a technical optimum, reduce the number of parts and speed up the manufacturing process.
