| 摘 要： | 本文从Holzer-Myklestad传递矩阵法出发,研究结构的频率、振型的变化率以及振型节点（或腹点）坐标的变化率。这对结构动力优化设计来说,使我们能够采用更有效的需用导数的优化方法。文中给出了算例,并与其它方法进行了比较,结果表明,本方法是可行的。

| Abstract: | Holzer-Myklestab transfer .mathed is one of the general methods which deals with the structural dynamic analysis, With the aid of the method the rates of change of the structural natural frequency mode shape and its node （or peak point） coordinate are studied in the paper. This enables us to use the more effi-cient optimal method by using derivatives for structural dynamic optimization The equations for the rate of change are derived in detail and the typical example is given in the paper.It's shown from computer calculation that its results coincide fully with calculating results of finite element method. Therefore, the present method is effective and applied efficiently to the engineering practice. |
