摘要

形状记忆复合材料（shape memory polymer composite, SMPC）是一种在航天领域具有广阔应用前景的智能材料。以重复折叠展开形状记忆历程后的五节SMPC可展桁架阵面天线为对象，进行自由状态下模态试验，通过模态参数识别得到自振频率和振型，研究了预应力索和阵面板对桁架模态的影响。结果表明，预应力索可提高桁架的整体刚度，并且提高了沿纵向的抗剪能力，而阵面板可提高桁架的扭转刚度。建立了考虑空气对阵面影响的声固耦合(acoustic structure interaction, ASI)有限元模型，进行五节SMPC可展桁架阵面天线模态分析，其结果与模态试验吻合，表明仿真分析方法准确。

Abstract

Shape memory composite (SMPC) is an intelligent material with promising applications in the aerospace field. The modal tests were conducted on a five-bay SMPC deployable truss array antenna after repeated folding and unfolding shape memory process, and the natural frequencies and mode shapes are obtained through modal parameter identification to investigate the influence of prestressed cable and array panel on structural dynamics. The results show that the prestressed cable can improve the overall stiffness and shear resistance of the truss antenna along the longitudinal direction, and the array panel can improve the torsional stiffness of the truss. An acoustic-structure interaction (ASI) finite element model which include the effect of air on the array surface is established for the computational modal analysis, and the results are in good agreement with the modal test, indicating the accuracy of the simulation analysis method.
