摘　　要：本文提出了一种贮仓结构参数的频域识别方法。本文在建立贮仓结构多质点体系计算模式的基础上 ,运用最小二乘识别理论 ,基于分析结果与试验结果的差别 ,迭代修正贮仓多质点体系中的参数 ,建立了贮仓结构参数的频域识别方法 ;并且 ,进行了贮仓结构的模态试验 ,实施了贮仓结构参数频域识别的全过程。计算结果表明 ,所建立的方法可产生良好的参数估计。The frequency domain identification method of the storehouse structure parameters is presented in the paper. On the basis of building the computation mode of the multi-freedom system of the storehouse structure, the frequency domain identification method of the storehouse structure parameters is established by using the least-square identification theory and correcting the deviation between the theoretical calculation results and the measured data. The frequency identification process is implemented by using the modal test data of the storehouse structure model. The computation result shows that the established parameter identification method can induce good parameter estimation.
