When the spacecraft structural dynamic model is updated using test data, the freedom of FEM can be matched with test freedom by means of reduction method.
利用试验数据修正航天器结构动力模型时，使用缩聚方法使有限元自由度与试验自由度匹配。
The dynamic calculations of the model and prototype structures are also made using structural finite element analyses programs and the results are compared and analyzed with the test.
同时，应用结构有限元分析程序对模型及原型结构进行动力计算，并将两种结果进行比较分析。
In this paper, the evaluation and analysis on the actual state of the steel structural traverse will insure its functions by the test on horizontal dynamic characteristics.
