ABSTRACT
The input data model of vehicle number 1 was written in substructure technique. In GENSYS the user has the possibility to write the input data in modules, so called substructures. The substructures in GENSYS are similar to subroutines in FORTRAN or procedures in ALGOL, PASCAL and C. Modeling this vehicle started with a substructure describing the wheelset with primary suspension. The bogie substructure describing the bogie-frame and the secondary suspension is shown. In the modeling of primary springs and traction rods the benchmark gave two alternatives: coupling elements with length or coupling elements without length. In GENSYS both alternatives are possible, but since the latter alternative was preferred, the actual model of vehicle number 1 was generated with couplings with zero length and a fixed line of action. The last part in modeling the vehicle consisted of setting values to the parameterized variables and setting properties to springs and dampers.
