In the “Vehicle Body 3DOF Longitudinal” block, the suspension parameters you mentioned relate to the forces and displacements within the vehicle's suspension system. Here's a brief overview:
- “FskF” refers to the front axle stiffness force data.
- “dzsF” pertains to the front axle displacement data.
- “FsbF” is the front axle damping force data.
- “dzdotsF” relates to the front axle velocity data.
These parameters are used to create lookup tables that calculate the front and rear suspension stiffness and damping. For instance, the front suspension stiffness is determined as a function of the stroke, using the values provided to the “FskF” and “dzsF” parameters. Thus, these vectors should have the same number of elements. Similarly, the front suspension damping is derived from a lookup table created with the “FsbF” and “dzdotsF” parameters.
