Abstract In this paper, a self-developed solver is used to numerically simulate the isolator section under complex inlet conditions, and influence of forced panel vibration on shock flow field in conditions investigated. The results show that has certain conditions.

A desirable characteristic for nonlinear vibration isolators is a high static stiffness and a low dynamic stiffness. A curved beam is a possible candidate for this role provided that the amplitude of vibration about the static equilibrium position is sufficiently small. However, for large amplitude oscillations, the nonlinear dynamics may have a detrimental effect. This paper considers the forc...

This report contains the results of a full-scale experimental feasibility study of rotor isolation employing the Dynamic Antiresonant Vibration Isolator (DAVI) . The full-scale experiments were performed on a UH-2 helicopter fuselage isolated from a simulated rotor and transmission. Tests were conducted for three directions of vibratory input at the hub on the nonisolated vehicle and then compa...

A floating raft system (FRS) is typically used for vibration isolation of shipboard machinery. Earlier investigations have analyzed the effectiveness of this system using progressive receptance/mobility based approaches. In this paper, a vibration power flow based approach in the framework of component mode synthesis (CMS) is proposed. Both fixed-fixed and fixed-free CMS formulations are compar...
