The TACRV Dynamics Simulation Program has been updated and specific suspension system analyses performed to reflect 'as built' vehicle dynamics. The two Phase programs which treated pitch plane and lateral dynamics separately are combined into one twenty degree of freedom model which has new models for the actuator/dampers, active suspension system, air cushions and sources of excitation. An analytical formulation of vehicle structural flexibility for future incorporation in the program is given. Sample program results for planned guideway perturbations are shown. Suspension system analyses cover the following areas: active suspension stability, nonlinear damping effects, and cushion pitch dynamics. Test results from the TACRV Ground Vibration Survey are presented. (Author)
