| 摘 要： | 根据刚体动力学原理、频响函数曲线的质量线理论，推导出表征刚体惯性参数的基本原理。然后提出频响函数的拟合方法，并通过误差分析，研究和改进试验方法及优化数据处理，对某圆柱形质量块惯性参数的测试值与理论值比较，标定整个测量系统的误差。最后以某型汽车动力总成为研究对象，基于试验模态分析技术完成该动力总成相关惯性参数的动态测试。

| Abstract: | Based on the rigid body dynamics principle and mass-line theory,the basal principle for identifying rigid body inertia parameters are deduced.Then the fitting method of FRF is given,the testing method is improved and the data processing is optimized by error analysis.Compare with the theory value and testing value of a cylinder mass inertia parameters,the measurement system's error is calibrated.Finally,take a automobile powertrain as an example,all inertia parameters are tested based on experimental modal ... |
