ENGINEERING DESIGN STUDY OF ACTIVE RIDE STABILIZER FOR THE DEPARTMENT OF TRANSPORTATION'S HIGH-SPEED TEST CARS

This report describes an engineering design study of the application of an active suspension to one of the U.S. Department of Transportation's high-speed test cars. The objective was to establish quantitatively the ride improvement which can be expected from the stabilizer as well as to determine power requirements, vehicle modifications, and the basic equipment design parameters. Quantitative assessment of expected ride improvement was carried out through computer simulation of the vehicle and the stabilization equipment for simulated sub-grade disturbances. These results are discussed in detail with computer records for the stabilized and unstabilized vehicle. To equip a test car with the proposed Active Stabilization System involves modification of the car suspension. These modifications are listed and detailed descriptions are given. (Author)
