Model Auditor
This tool audits a full-vehicle model using user-entered tolerances. The results are displayed on screen and saved to a text file. The following model characteristics can be checked:
1. Solver settings.
2. Beam element length less than diameter for stabilizer bars, twist beam axles, and beam trailing arms. For cross-sections that are not circular, the "diameter" is calculated as 2*SQRT(area/
).
). 3. Part inertias are physically meaningful. The following are checked: IXX + IYY >= IZZ, IXX + IZZ >= IYY, IYY + IZZ >= IXX.
4. Front suspension, rear suspension, steering and powertrain part CG locations relative to the default CGs using a user-entered tolerance.
5. Bushing location coincident with ZP/XP locations.
6. Bushing rates. If the bushing uses linear stiffness and linear or Kfraction damping, check against user-entered upper and lower tolerances.
7. Bushing stiffness compared with a user-entered stiffness limit.
8. Splines in springs, airsprings, dampers, and bushings. Check for proper sign convention, proper slope, and 2nd derivative less than a user-entered limit.
