Importing of calculation routines from DRESP to SIMPACK



The imported user-defined force elements to SIMPACK permit the representation of torsional vibration systems in a multi-body environment with almost all degrees of freedom and detail levels, and thereby enabling a full investigation of dynamic system behavior.


Simulation technologies are increasingly being deployed in the drivetrain technology sector for purposes of shorter development time, increased cost pressure, and higher quality standards. DRESP is a simulation tool for simulating dynamic systems, and contains very valuable calculation routines in the form of coupling and excitation elements from over 35 years of extensive research. The know-how from DRESP has been preserved by importing it to SIMPACK.

Research objectives

The objective of this research project is importing existing DRESP calculation routines as new elements and libraries for user-defined forces in SIMPACK that are specially tailored to the simulation of drivetrains. The following goals were pursued:

  • Using DRESP calculation modules as the basis for development of the user-defined force elements
  • Avoiding unnecessary repeated developments
  • Preserving the know-how of the calculation methods for the future
  • Product adjacent modeling using the calculation routines known from DRESP
