✦ Synopsis

The Melnikov criterion is used to examine a global homoclinic bifurcation and transition to chaos in the case of a quarter car model excited kinematically by the road surface profile. By analyzing the potential an analytic expression is found for the homoclinic orbit. By introducing an harmonic excitation term and damping as perturbations, the critical Melnikov amplitude of the road surface profile is found, above which the system can vibrate chaotically.

The physical understanding of ground/structure vibrational interaction is essential in order to relate ground vibration levels outside buildings to structural vibration levels in buildings. A 2-D FEM/BEM computer program has been developed and is used to study the simple problem of surface excitatio
