This project is a continuation of MOU387. It continues the research of two
important aerodynamic components for heavy-duty vehicles. The first task is to
carry out wind tunnel measurements
of drag and potential fuel savings for two scale-model tractor-trailers in
tandem at short headway. The second task is to derive sufficient vehicle roll
stability margin for safe handling of Class 8 trucks at high speeds and under
strong cross-wind and abnormal road (such as wet highway) conditions. The
measurements will be made on static tractor-trailer configurations, and will
yield estimates of the quasi-steady limit forces.
