摘要

针对舰船振动噪声低频（100Hz以下）线谱重构问题，提出了一种含半主动作动元件（磁流变阻尼器）的滞回非线性基座结构，并给出了基于MRD电流调节的舰船振动低频线谱重构方法。首先，基于Bouc-Wen滞回非线性模型建立起了新型基座结构的运动方程并开展了数值仿真分析，发现MRD的引入在使基座振动出现了分岔、混沌特征，这为舰船振动线谱重构奠定了理论基础；为进一步验证所提滞回非线性基座的低频线谱重构效果，搭建了缩比模型试验平台并开展了线谱重构试验。试验结果表明：40组工况中线谱幅值降低效果平均达到49.8%，最大可达90.7%。

Abstract

Aiming at problems of low frequency (below 100Hz) line spectrum reconstruction of ship vibration and noise, a hysteretic nonlinear base structure with semi-active actuator (Magnetorheological Damper) and a method of low frequency line spectrum reconstruction based on current regulation of MRD was proposed. Based on Bouc-Wen hysteretic nonlinear model, the motion equation of the new base structure was established and the numerical simulation analysis was carried out. The results show that the introduction of MRD makes the base vibration appear bifurcation and chaos characteristics, which lays a theoretical foundation for the reconstruction of ship vibration line spectrum. In order to further verify effects of line spectrum reconstruction, a scaled model test platform was built and the line spectrum reconstruction experiment was carried out. The results show that the average reduction effect of line spectrum amplitude is 49.8%, and the maximum is 90.7% in 40 groups of working conditions.
