| 摘 要： | 根据采用振动台环境试验数据,得到了以振动台台面与被测对象之间连接点为激励点,测点为响应点的被测结构频率响应函数,从而获得了结构的模态参数。以模态试验的结果作为衡量标准,验证了利用振动试验的力控数据进行模态分析的正确性和可行性。

| Abstract: | Based on the data of vibration environmental test,the acceleration transfer function and the generalized frequency response functions(GFRFs)were obtained.The link points between the base table and the items were the exciting source.Then,the modal parameters of the structure were acquired.The results of the modal test were used as the criterion to validate the correctness and feasibility of the modal analysis based on the vibration test data from Force Limited Vibration Testing. |
