The presented results are generated by a project with the title „ Development tools for railway carriages with ponents“. The project
was funded by the German Federation of Industrial Cooperative Research Associations „Otto von Guericke“(AiF-Nr. 12074 B/1), on behalf of The
Federal Ministry of Economics and Technology (BMWi), in the Section Fluid Power of the German Engineering Federation (VDMA).
