| 摘 要： | 通过结构模态试验和小量级振动试验,获得有效反应真实结构特性的有限元模型,并利用简化的两自由度振动系统和小量级试验数据分析,预示出振动系统在反共振点进行力限(加速度带谷)的条件。为工程中抑制过试验问题,进行力限条件控制提供了重要依据和参考。

| Abstract: | In this paper, the force limited （acceleration notching） qualification was obtained by model accounted and analyzed the date of low-level test, and the FEM model of structure which could indicated the real structural characteristic obtained by modal test and low-level test and two degree-of-freedom system analyse. It offered an important gist and reference to force limited control for avoiding overtest in the project. |
