Multibody dynamics (MBD)

By means of multi-body dynamics (MBD) complex kinematic systems can be examined and optimized with regard to their functionality.
Within these systems, the dynamic cutting forces occurring due to external excitation can be determined and used as input variables in subsequent structural-mechanical FEM calculations.

We offer you:

  • Kinematic analyses
  • Dynamic cutting force determination
  • Transient dynamic analyses

Cutting force curves on a MTB frame due to excitation at the wheel base points


Provided that a solid load base is available, it makes sense to perform topology optimization at an early stage of the design process. The best possible structure for the given requirements is determined, which results in an optimal material distribution and thus a minimum component weight.

We offer you:

  • Topology/topography optimization
  • Shape optimization
  • Parameter optimization / DOE
  • Lattice optimization

Topology optimization of a MTB frame

Topology optimization of a leveling component from a crane

Stiffness / strength simulation

The structural-mechanical calculation using the Finite Element Method (FEM) has become one of the standard tools for reliable component development. With this method, projects can be investigated quickly and cost-effectively, purely virtually, with regard to their mechanical properties. Expensive prototypes are therefore only used at the end of the project.

We offer you:

  • Linear static analyses
  • Nonlinear static analyses (geometric / material nonlinear)
  • Modal analyses
  • Transient dynamic analyses
  • Thermomechanical analyses (stationary + transient)

Strength calculation of a MTB frame and a leveling component from a crane

Fatigue strength simulation

Knowing the strength of a component under maximum load does not allow any statement to be made about its durability. For this purpose it is necessary to consider the fatigue strength under a discrete load spectrum.

We offer you:

  • Creation of a load spectrum
  • Fatigue strength analysis
  • Damage analyses

Damage distribution on a MTB frame

NVH simulation

Based on the calculation methods of FEM, acoustic and vibration relevant problems can be investigated. The NVH (Noise Vibration Harshness) field is focused on detecting, reducing or, if possible, eliminating noise and vibration sources that are disturbing to humans at an early stage of development.

We offer you:

  • Modal analyses
  • Complex eigenvalue analyses
  • Frequency Response analysis (FRA)
  • Random response analysis (RRA)

Acoustic emission (structure borne noise) of a motorcycle silencer via speed and frequency

CFD simulation

Computational Fluid Dynamics (CFD) calculations can be used to investigate fluidic issues such as flow velocity, flow direction, or flow- and pressure distribution. This applies to laminar as well as turbulent flows in various media. Furthermore, the forces generated by the flow on a component and the resulting interactions (fluid-structure interaction) can be determined.

We offer you:

  • Flow analysis (turbulent, laminar)
  • Fluid-structure interaction

Streamlines and pressure distribution in a motorcycle silencer with four chamber system

DEM simulation

The Discrete Element Method deals with the simulation of a large number of particles that are in contact with each other. Thus it is possible to calculate the dynamic behaviour of granular media such as sand, powder, earth or also rock, and their interaction with surrounding components. Typical applications are e.g. sieving, mixing, transporting, or even crushing of arbitrary solids.
Furthermore, the range of applications of DEM can be extended by co-simulations with CFD, MBD, or FEM.
Numerous examples of application in geotechnics, agriculture, or medical technology can be found under the following link:
