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，供读者应用时参考
The control method of the vibration test of the large component test piece is the key to test success and ensure the accuracy of the test. For each experiment, it is difficult to treat with a fixed control mode due to the different structural parameters of the components. Based on the research and analysis of the response characteristics of the test items, the advantages and disadvantages of several control methods are compared to determine the effective and feasible control methods. The author combines the practice of a project test, discusses the method of research and analysis for reference readers
