ABSTRACT
This article is devoted to the methods of designing running gear in compliance with recently changed requirements, regulations of rail authorities, technical specification for interoperability, and safety certification. Changes are focused on the certification process. According to ERA these changes are recommended for bogies holding IC certificate issued according to the former TSI WAG, without assessment of the strength of the bogie frame.
The presented methods allow designing a bogie platform with a wide range of applications in regional, and long-distance trains. Issues related to calculations, and studies of bogie frames are described. Particular attention is paid to methods for determining loads applied to the bogie frame based on assumed axle loads, determining reference forces for the projected shock absorbers, and compiling computational cases for strength analysis of traction units.
