System Simulation

In system and vehicle development, it is essential to simulate the physical system properties at an early stage in each of the different phases of the development process. This is required to evaluate, improve, and safeguard the designs.


For example, the motor dynamics, drive dynamics, vibration comfort, durability, and behaviors of assistance and safety systems must be calculated. Additionally, different complexities of the model and computational speeds are required for the various tasks and the different phases. Increasingly important is the possibility of hybrid and interactive simulation to integrate the electronic controls and the driver realistically into the computations.

 

What we are working on:

  • Further development and application of Multi-Body Simulation (MBS) methods
  • Regulation and optimal control of technical systems
  • Simulation of coupled physical systems (co-simulation)

A special focus is on real-time capable methods for applications in driving operations, in HiL-/SiL areas, and in the area of interactive driving simulators.

 

 

Invariant Excitations

For the computer simulation of dynamical systems, a mathematical model of the real system is needed as well as an input- or excitation-model that describes properly the interface between the considered dynamical system and its environment.

 

Real-time Simulation and simulation-based Monitoring

In all real-time applications, the interplay of modeling, model complexity, and numerics is of great significance.

 

Coupled Simulation

Today, the coupling of simulation software from several different physical domains is essential to adequately map and simulate modern technical systems.

 

Driver and Operator Modeling

The influence of the driver or operator of vehicle or equipment is significant with respect to operational durability, energy, resource efficiency and safety.

 

Component Loads and Virtual Test Rigs

An essential prerequisite to ensure correct stress-related dimensioning of components is having knowledge of the cutting stresses on the component.

 

Simulation of Soil-Tool Interaction

The high variability of construction and agricultural machinery leads to high demands on the product development.
