– Geometric modifications to the castings to avoid stress concentrations.

– Finite element analysis (Nastran and LIMIT®) was used to ensure durability over the planned 30-year service life.

The development project was carried out by Bombardier Transportation in cooperation with CAE Simulation & Solutions and the end customer. The pictures show the FE model as well as the occurring displacements and stresses.
