Astec - Case Study

Roadtec, Inc. manufactures material transfer vehicles (MTVs) that enable nonstop, noncontact road paving. The MTVs are delivered to job sites on flatbed trucks that can reach speeds of 70 mph. Depending on the flatbed operator, the MTVs may be loaded facing forward or backward. To design a safety restraint system that would protect both front- and back-facing MTVs, engineers had to model the airflow patterns associated with both configurations.
