FEMFAT LAB model improvement
Features Overview:
- MBS-model parameters will be improved based on RLD (measured channels at the structure, e.g. accelerations, relative displacements or forces)
- Excitation is well known (measured or computed by VI) and fixed during investigations
- Parameters must be defined and will be updated
- A diagnose tool assists to identify the relevant parameter
Usual dynamic simulation process
Virtual iteration
Model improvement
Diagnose - identify relevant parameters
e.g. based on relative damage values of simulated signals compared to measured signal, high deviation from value one means high influence
MBS-model parameters which can be automatically improved:
- Mass, center of gravity
- Mass moment of inertia
- IX or IY or IZ
- Common factor on IX, IY and IZ
- SFORCE
- Stiffness by value or spline (linear factor), translational (e.g. coil spring) or rotational (e.g. stabilizer)
- Damping by value or spline (linear factor), translational or rotational
- VFORCE, GFORCE, FIELD (bushing)
- Stiffness by value or spline (linear factor), common factor for all directions or directions separately
- Damping by value, common factor for all directions or directions separately
