MBS (multi-body simulation, also: multi-body system) enables the description of complex, mechanical systems with relatively moving individual bodies using structurally simplified models. It is used where conventional methods such as FEM are not economically feasible and therefore provides a valid basis for decision-making on highly complex issues.
We provide you with a complete FMD package including analytical preliminary considerations, the implementation of the FMD and the interpretation of the results. As a result, you receive actionable suggestions for action.

A MBS is required to analyze the dynamics of systems with multiple moving bodies. Such systems can exhibit complex motions, forces and moments that can only be covered with great effort or accuracy by conventional methods such as the finite element method (FEM) or analytical mechanics.

The complete package for multi-body simulation
We see ourselves as a full-service FMD service provider for this demanding method. We are guided by the following steps, which we carry out carefully in order to achieve precise and reliable results:
System definition
We define the physical quantities, the moving bodies and their properties and decide whether simulations in other physical disciplines should be integrated as a stimulus.
Modeling
We create the MBS model by defining the bodies, connections and forces that act on the system.
Airborne sound simulation
For the explicit prediction of acoustics, we extend the overall model to include the simulation of airborne noise (so-called ATV+MATV). We determine noise character, radiation behavior, level and main contributors, etc.
Solution of the system of equations of motion
We use numerical methods to solve the equations of motion of the system in order to determine the dynamics of the bodies over time.
Validation
We validate the model against experimental data or comparative solutions to ensure that the model correctly represents the real system.
Analysis and optimization
The results of the simulation are analyzed in order to gain important insights into the behavior of the system and, if necessary, to suggest optimizations.
"The integration of the complex multi-body simulation reduced the project lead time. We were able to evaluate significant changes quickly and efficiently in advance in a simulation and draw appropriate conclusions."
