DEVELOPMENT OF AERODYNAMIC DISTURBANCE TEST PROCEDURES. VOLUME I: EXECUTIVE SUMMARY
Research described in this report was conducted using the first full scale crosswind disturbance test facility in the United States. This facility is capable of providing a 35 mph crosswind for a nominal 120 ft test length. The crosswind responses of twenty different vehicles were surveyed. These vehicles included 8 conventional cars (plus 4 trailers), 2 station wagons, 3 light trucks (one with camper), 3 vans, and 4 two-wheelers (including a moped and bicycle). Complete instrumented vehicle tests were conducted on five vehicles: Honda Accord, Chevrolet station wagon (alone and with trailer), Ford Econoline van, VW Microbus, and Ford pickup/camper. Three test procedures were used in three different crosswind disturbance configurations. These were steering fixed, steering free, and driver control of lane position. The crosswind configurations were straight pulse, doublet pulse, and a shaped profile. Results showed that passenger cars, station wagons, trucks, and most vans have virtually no crosswind sensitivity problems, whereas the VW Microbus, the pickup/camper (in winds higher than 35 mph), cars pulling trailers, and mopeds do have potential problems.
