摘要

摘要: 提出了一种隔振圈结构等效建模方法，并使用ANSYS建立了包含动力装置、隔振圈及动力舱壳体在内的动力舱段振动分析模型。计算与试验对比表明，本文模型能够较好地反映出动力舱段的结构振动传递特性。利用本文模型开展参数影响分析，结果表明：动力装置的简化程度过大会引起舱段壳振动响应计算结果的较大误差；减小隔振圈径向刚度、增大壳体阻尼有助于降低壳体较高频段的振动响应，但对抑制低频振动无显著效果。

Abstract: An equivalent modeling method of ring isolator was proposed, and a vibration analysis model of dynamic cabin, which included power unit, ring isolator and cabin shell, was established using ANSYS. The simulation results were compared with the experimental ones to show the validity of the finite element model. Effects of some major parameters on vibration transmission characteristics were discussed. The parameter study result shows that large error will occur with high simplification degree of power unit; decreasing the radial stiffness of ring isolator or increasing the structural damping of the cabin shell can reduce structural vibration response of dynamical systems in high frequency band, but they have no significant effect on anti-vibration in low frequency band.
