Abstract
The conical rubber springs manufactured by Trelleborg-Industrial AVS is a
primary suspension layout used between the bogie frame and the axle box for
railway vehicles. The system is subjected to both static and fatigue loads. Both
FE analysis and experiments are required to assess the strength and durability of
the metal parts of the system. Also the stress profile will indicate where the strain
gauges should be located when actual experiments are conducted. The geometry
of the component is imported from CAD system to CAE system. Care has been
taken to provide a sufficient fine grid to give reasonable results when mesh of
the part is generated. Static and fatigue load cases are evaluated separately. Von
Mises criterion has been used to evaluate the stress state under the loading
conditions. The critical loca
