摘　　要：含垫层压紧结构占有空间小,便于安装拆卸,利于内层部件保护等特点,现已广泛应用。介绍了一种含垫层压紧结构,开展了其零件与整体结构的模态试验分析,获得了各零件一阶模态频率与预紧载荷下整体结构的低阶模态频率、阻尼比、振型,可为提高结构振动环境适应性改进或优化设计提供试验依据。Impacting structure contained silicone rubber was used in engineering widely for little occupancy, easy to be assembled, easy to be dismantled and in favor for protecting inner body. A kind of impacting structure contained silicone rubber was presented in this paper. The study of modal experiment was done on part and whole structure. Modal parameters were obtained by analysis. The result of EMA could afford data reference to increase the capability of impacting structure adapted for vibration environment and to optimization design.
