DYNAMICS ANALYSIS OF A FLEXIBLE VEHICLE-FLEXIBLE GUIDEWAY SYSTEM WITH RANDOM GUIDEWAY ROUGHNESS INPUT

A technique is developed for analyzing the coupled dynamics of a two-dimensional high speed guided ground vehicle system consisting of a flexible vehicle propelled along a single-span, flexible guideway. Both vehicle and guideway are treated as Bernoulli-Euler beams, the former in free-free configuration and the latter with simple, rigid end supports. A modal analysis technique is implemented to calculate their respective transverse flexural motions. The analysis provides for the incorporation of any number of transverse, flexural modes for the vehicle and guideway. Vehicle aerodynamic drag force is also included in the system model. The vehicle features symmetric front and rear suspensions with linear, active control systems sensitive to vehicle-guideway separation magnitude and separation rate.
