大型构件试品振动控制方法研究

Research of Structure Vibration Control Methods Nanjing Research Institute of Electronic Technology

大型构件试品振动试验的控制方法是试验成败和确保试验准确度的关键。每项试验由于构件形式结构参量各不相同很难以一种固定的控制模式对待，必须在对试品响应特性的研究分析的基础上比较若干控制方法的优劣，以确定有效可行的控制方法。本文作者结合某项工程试验的实践，论述研究分析的方法。

Control method is key to feasibility and accuracy of large structure vibration test. Due to its complex dynamic responses,control methods should be compared and proper methods chosen to make the test successful. Based on a engineering problem,several control methods are analysed in this paper.
