The importance of elevated guideway/vehicle dynamics to the design of advanced high-performance ground transportation systems is discussed and the general coupled vehicle-suspension guideway interaction problem is described. Simplifying assumptions valid for many practical dynamic analyses are described including the Bernoulli-Euler beam assumptions, support conditions and simplified vehicle models. It is shown for high-performance systems where passenger compartment accelerations are less than about 0.05 g and vehicle unsprung to sprung mass ratios are small that guideway deflections can be accurately computed assuming the vehicle exerts on the guideway constant suspension forces which traverse the guideway at the vehicle forward velocity. Dynamic motions of the vehicle can then be computed by standard transfer function methods using the guideway deflection as a known input to the vehicle suspensions.
