摘要
提出一种基于实测传递函数矩阵来识别机械结合面阻尼参数的新方法。该方法不涉及机械结构的质量矩阵和刚度矩阵，从而避免了这两种矩阵建模误差对阻尼参数识别精度的影响。
A method to identify the damping parameters of machine joint surface is proposed based on the tested frequency response functions. The identification precision of the method is not influenced by the modeling errors of the mass and stiffness matrix of machine structure, whereby the effects of the modeling errors of these two matrixes upon the identification accuracy of damping parameters are avoided.
