Joint modelling for system simulation



The optimization of acoustics, comfort and resource efficiency is becoming more and more relevant in the product development of technical systems. In addition to the goal of functional fulfilment, the acoustic and tangible comfort properties summarized under the term Noise, Vibration, Harshness (NVH) are increasingly moving into the focus of customers. The ability to dampen vibrations plays an essential role in acoustic behaviour. In the case of two-dimensionally connected structures, the major part of the damping occurs in the connection points of the components - the joints. There are currently no suitable models for depicting this behaviour in system simulations.


Research objectives

The aim of this project is to provide a methodology for the computationally efficient consideration of the joint damping in the system simulation. The solution is based on the reduction of the spatially high-resolution modeling of the joint, calibrated by means of measurements on the prototype, to a concentrated description that can map the non-linear contact behavior of larger areas within the framework of the system simulation in a computationally efficient manner. The objective is divided into the following aspects:

  • Identification of suitable levels of detail in the joint modeling depending on the structural design of the joint
  • Development of computationally efficient models with suitable levels of detail as well as suitable parameterization methods
  • Deriving a method guide
