提出一种利用实验测试的平移自由度机械导纳估算所需要的旋转自由度机械导纳。其基本思想是在需要转换的点上布置加速度传感器，在测点处激励并提取各点的机械导纳。然后通过转换矩阵将这些平移自由度机械导纳转换为旋转自由度机械导纳机械导纳。通过对一悬臂梁结构的旋转自由度机械导纳的解析解和测试值进行对比。结果显示本文提出的测试方法具有较高的精度，可以较好的满足工程需求。

This paper propose the experimental derivation of rotational degree of freedom (dof) of mechanical mobility from translational dof of mechanical mobility. Accelerometers are located at the point where rotation needs to be de-rived, translational mobility measurements are made. Then, formularize the relationship between rotations and transla-tions by transformation matrices. The comparison of rotational parameters by the analytical method and the measure-ments for a cantilever beam shows the test error is small, satisfying the engineering application.
