本文针对机械结构动力修改的特征导数法（ＥＤＭ）所存在的问题，提出逆特征导数法（ＩＥＤＭ）。计算实例表明，该方法计算量小、精度高，在实际应用中更加方便、有效。
In this paper, inverse eigen derivative method (IEDM) is proposed to solve the problems existing in the EDM of mechanical structure dynamics. The calculation example shows that the method has the advantages of small calculation and high precision, which is more convenient and effective in practical application.
