The steady state, geometrically non-linear, periodic vibration of rectangular thin plates under harmonic external excitations, is analyzed using the hierarchical "nite element and the harmonic balance methods. Modal coupling due to internal resonance is detected and the consequent multi-modal and mu

โฆ Synopsis
An analysis is presented,for multi-stage multi-mesh gear transmission systems which predicts the overall system dynamics and transmissibility to the gear box or the enclosed structure. The modal synthesis approach of the analysis treats the uncoupled lateral/torsional modal characteristics of each stage or component independently. The vibration signature analysis evaluates the global dynamics coupling in the system. The method synthesizes the interaction of' each modal component or stage with nonlinear gear mesh dynamics and modal support geometry characteristics. The analysis simulates transient and steady state vibration events due to torque variations, speed changes, rotor imbalances and gear box support motion excitations. A vibration signature analysis scheme examines the overalldynamic characteristics
