基于网架结构周期特性的改进设计及振动传递特性分析
Analysis of Vibration Transmission Characteristics for an Improved Space Truss Structure Based on the Periodic Characteristics
摘要
Abstract
[Purposes]In this paper,the dynamics of the three-dimensional periodic lattice cluster structure is analyzed to explore the internal relationship between the design of different periodic ele-ments and the macroscopic global characteristics.[Methods]The finite element method was used to es-tablish the space truss model and its vibration isolation performance was evaluated by calculating its fre-quency response characteristics.Two kinds of space truss structure model were designed according to the band gap principle of periodic structure,namely the spiral rod space truss structure and the double material space truss structure,and the vibration isolation effects of the models under different designs were calculated and analyzed.[Findings]The results show that compared with original space truss structure,the designed two kinds of structure can suppress the high frequency vibration.Moreover,the analyses of the band gap characteristics in the periodic characteristics of the space truss structure can also provide a theoretical basis for the health monitoring and vibration control of this kind of structure.关键词
