【摘要】 文[1]对时变多数结构的动力响应计算，用Hamilton定律推导出了算法公式，其中对响应、质量、刚度和阻尼均使用了三次Hermite插值，但只给出了对单自由度问题的应用，具有实际的应用价值的算法应该可以解决多自由度问题。对此进行了研究，针对一个两自由度的问题给出了算法的验证，与此相仿的所有多自由度问题就都可以应用了。更多还原

【Abstract】 In [1] authors calculated dynandc response for time variant parameter construction, and concluded an algorithm formula by means of Handlton law. In the process of conduding formula three times Hermite interpolation for response, quality, spiffness and bamping were used, but only the application of single BOF problerns is given. Algorithm with application value should solute many BOF problerns. The authors give a test on algorithm of two BOF problems. Sindlarly, many BOF problerns can be applied.更多还原
