摘要
提出了一种结构惯性参数测试、识别方法。采用试验模态分析技术，将被测结构柔性悬挂，对结构激振，测量激振力和响应，经信号处理、参数识别，最后可得到结构的质量、质心坐标、主惯性矩、惯性主轴等全部惯性参数。某直梁的计算机仿真计算及实际测试结果表明本文提出的理论方法是正确的、有效的。
A new technique to measure structural inertia parameters is presented in this paper. The structure to be measured is flexible supported,Using dynamic test equipment,the structure is excited,responses and forces are measured.Through signal analysis and parameter estimation,all inertia parameters of the structure can be obtained.Simulation and application of a beam dem-onstrate that the technique presented here is feasible effective,and very useful in many fields.
