船用新型蜂窝隔振器减振性能分析
Performance Analysis of a Novel Marine Honeycomb Vibration Isolator
摘要
Abstract
Honeycomb structures are well-known for their unique in-plane loading characteristics on vi-bration reduction and shock absorption. In this paper,two types of composite hexagonal honeycomb vibra-tion isolators with positive and negative macro Poisson's ratios are designed respectively. The proposed iso-lators can also serve as mountings in certain applications. To investigate their actual properties,the finite element models for these honeycomb isolation systems are established,and their vibration reduction capa-bilities are demonstrated through both modal analysis and frequency response analysis. The results reveal a 17 dB difference in the vibration level when using the proposed isolators in the lower frequency domain from 1~50 Hz. Meanwhile,comparative studies are conducted for the isolators with either composite mate-rial panels or steel panels,and better mechanical performance on resonance restrain is observed for the for-mer ones.关键词
