Theoretical Explanation for Lower Order Harmonic Resonance Phenomenon of Three-Ring Gear Transmissions

摘要

Dynamic investigations revealed that lower order harmonic resonance phenomenon exists in the three-frequency of the transmission, the loads on the bearings and gears are especially high. This paper explained thisphenomenon from the viewpoint of parametric resonance in terms of perturbation technique. A conclusion wasdrawn that the basic reason for this phenomenon is the primary resonance caused by forcing excitation and para-metric resonance caused by parametric change.
