Abstract

Abstract: This paper focuses on the primary resonance analysis of a dual-rotor system considering the two rotor imbalanced excitations with different rotating speeds, the radial clearance of the inter-shaft bearing and the maneuver load. The vibration equations of the dual-rotor in the hover flight environment are formulated using the Lagrange equation. The primary resonance responses are then obtained by numerical methods, followed by the investigation into the primary resonance characteristics under the influence of the maneuver load and the clearance of inter-shaft bearing. The results reveal that the dual-rotor system has some typical nonlinear dynamic behaviors, such as vibration jump and bi-stable phenomenon. The maneuver load exerts a "stiffness enhancement effect" while the inter-shaft bearing clearance a "stiffness weakening effect" on the dual rotor system.

Key words: maneuvering flight, dual-rotor system, primary resonance, vibration jump, bi-stable
