Development of a secondary spring for a trailer bogie

An hourglass spring was to be developed for a trailer bogie of a metro for the secondary suspension of the vehicle, with special attention being paid to low lateral stiffness of the spring system.

 

Solution approach:

For this purpose, we conducted extensive concept and design studies using finite element analysis (FEA) and evaluated the service life based on multi-body simulation (MBS) data using our software DACA.

Results:

For our customer, we were able to develop a suspension element in the specified design space that meets the requirements for lateral and vertical stiffness as well as service life.
