| Abstract: |
The
analytical target cascading process is applied to the redesign
of a U.S. class VI truck. Necessary simulation and analysis models
for predicting vehicle dynamics, powertrain, and suspension behavior
are developed. Vehicle design targets that include improved fuel
economy, ride quality, driveability, and performance metrics are
translated into system design specifications, and a consistent
final design is obtained. Trade-offs between conflicting targets
are identified. The study illustrates how the analytical target
cascading process can reduce vehicle design cycle time while ensuring
physical prototype matching, and how costly design iterations
late in the development process can be avoided. |
