摘要
通过模态试验和振动台试验,对复合材料蜂窝结构锥形壳的振动传递特性进行了研究。理论分析和试验结果表明:该结构隔振频带宽、模态阻尼比大,具有大阻尼隔振系统的特征,能够有效的控制振动的传递率。复合材料的应用在保证结构可靠性的前提下进一步降低了结构系统的质量。
The vibration transmissibility of the conical shell with composite material honeycomb structure is investigated by modal experiment and vibration table experiment. Theoretical analysis and experimental results show that the experimental structure has a higher modal damping ratio, and can effectively control the vibration transmissibility in a broad bandwidth, which is the characteristic of vibration isolation system with high damping. The application of composite material reduces the weight of the whole system without sacrificing the dependability of structure.
