The key value of Model Based Development is to realize capability of quick performance design and simulation at the early phase of development. In this paper, we modeled an arc spring type torsional damper, which has an impact on the torsional vibration characteristics of powertrain in a vehicle. To predict non-linearity of the arc springs, we took a discrete modeling approach using MODELICA and compared its simulation results with the physical test results. We also developed a user-friendly interface with FMIE (Modelon FMI Add-in for Excel) so that a non-expert of physical modeling can run performance design easily and precisely on their own.
