本文提出了一个数学模型，用于解决工业启发的应用于弹性流体填充容器的隔振问题。解决了多尺度流固系统有限宽度频率区间内振动抑制的基本问题。我们开发了一种采用完整流固相互作用和色散分析的系统方法，可应用于有限和周期性的多尺度系统。分析结果附有数值模拟，包括频率响应分析和瞬态状态计算。 (C) 2016 Elsevier Ltd. 保留所有权利。
This paper presents a mathematical model for an industry-inspired problem of vibration isolation applied to elastic fluid-filled containers. A fundamental problem of suppression of vibrations within a finite-width frequency interval for a multi-scale fluid-solid system has been solved. We have developed a systematic approach employing full fluid-solid interaction and dispersion analysis, which can be applied to finite and periodic multi-scale systems. The analytical findings are accompanied by numerical simulations, including frequency response analyses and transient regime computations. (C) 2016 Elsevier Ltd. All rights reserved.
