DRESP: A simulation program for determining torsional vibrations in drivetrains

 

Results

DRESP is a simulation program with 126 calculation modules, which resulted from 14 PhD dissertations. DRESP has a user-friendly program interface, a high-performance solver, and an interface to the FVA workbench.

Motivation

The growing demand for a simulation tool for analyzing torsional vibration behavior of the dynamical systems motivated a number of research projects, which resulted in the development of DRESP. The interest of over 100 industry partners drove its continuous improvement and expansion. The calculation modules added later were developed as parts of requirements from dissertations, research and industrial projects.

Research objectives

The development and further improvements of DRESP were carried out with the aim of obtaining a universally applicable, powerful, and efficient tool for the development and analysis of the dynamic behavior of drivetrain systems containing different excitations and coupling components. The following goals were pursued:

  • The collection and sharing of methods and algorithms from numerous research projects and PhD dissertations
  • Calculation of time- and position-dependent torsional loads on each component of the drivetrain
  • Determining the loads on locations in the drivetrain which are otherwise undetectable by measurements
  • Consideration of linear and non-linear excitations and transfer paths, not just for torsional degree-of-freedom
