摘要
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, an inverse eigen derivative method (IEDM) for dynamic modification of mechanical structures is formulated for improving the eigen derivative method(EDM). Two examples verify its simplicity and precision, and it is more useful in application.
