中文摘要:
把作者近期提出的用于频响函数计算的级数展开法进行了推广，使其计算精度进一步提高，并且能适用于自由－自由系统。数值示例表明，本文提出的方法是有效的。
英文摘要:
A new method for calculating frequency response function is derived by extending the Series Expansion Method(SEM) which was proposed by auther, recently. The new method is more accurate than SEM and can be used for free free systems. Numerical examples demonstrate that the new method is efficient.
