• ### Modal Analysis: Mass Participation

In the Modal Analysis user has the objective of obtaining the frequencies and shapes of each mode. As the number of eigenvalues to be calculated has to be given it is the Cumulative Effective Mass Participation Factor (CEMPF) in each direction that is…

• ### Modal Analysis: Eigenvalues

The calculation of Eigenvalues is the first step in many dynamic calculations. Despite it involves advanced structural engineering concepts not always studied in deep in some civil engineering courses it is quite simple to do frequencies analysis in RM…

• ### Rolling Stock Analysis: Track Interaction Springs for HSR

TIS - Track Interaction Springs are complex spring elements where the constitutive relation of the shear terms is variable and bi-linear. It depends on the limit force F that separates the unloaded from the loaded case. Then spring contacts for the shear…
