中文摘要：

基于一种新型惯性元件——惯容器，设计一种新型动力反共振隔振器，研究该隔振器的低频线谱隔振性能，为舰船动力设备的低频线谱隔振研究提供新思路和理论借鉴。考虑隔振基础的非刚性，建立了此种隔振器的动力学模型，分析了系统的动力学特性和振动传递特性，讨论了相关元件参数（弹簧刚度，阻尼系数，惯容值等）对隔振器隔振性能的影响。分析表明并联惯容器后可使隔振器的固有频率降低，使得隔振器具有更低的隔振频段；同时可形成一个反共振频率，当激振频率在该反共振频率附近时具有优良的隔振性能，从而实现良好的低频线谱隔振。

英文摘要：

Based on a new type of inertial element also known as an inerter, a novel dynamic anti-resonance isolator was designed and its low-frequency line spectrum vibration isolation performance was researched. This research was conducted to provide a new idea and theoretical reference for the research on low-frequency line spectrum vibration isolation performance of power equipment in a vessel. The mathematical model of isolation was deduced for the analysis of vibration transmission characteristics with the consideration of the flexibility of the isolator's base. Then, the influence of element parameters (spring stiffness, damping coefficient and inerter, etc.) on the vibration isolation performance was discussed. The analysis shows that the natural frequency of the vibration isolator can decrease after the inerter is introduced into the system in parallel connection, and the anti-resonance frequency is decided by the inerter at the same time. When the excitation frequency is close to the anti-resonance frequency, the isolator has good vibration isolation performance, realizing excellent low-frequency line spectrum vibration isolation performance. ? 2016, Editorial Department of Journal of HEU.
