摘要
对三维强化抛光振动台的初始结构模型进行试验模态分析,获得各阶模态参数,分析其结构动力特性,并与有限元模态分析结果进行对比,验证有限元模型的正确性。进而为实现结构的优化设计提供依据。
This paper accomplishes the experimental modal analysis for the original structure model of the installation,obtains the parameters of every order mode,analyzes the structure dynamics of the installation,compares the finite element results with the experimental results,verifies the correction of the finite model,offers the references of further optimization design.
