一、引言用来校核动态分析结果的正确性,验证和调整数学模型以及鉴定总体设计是否合理的振动试验,随着测试设备、分析方法和分析手段的不断改进,近年来发展极为迅速。由于电子计算机在振动试验中的应用,使振动试验中的过程控制、数据分析、试验过程中的自动化等日趋完善。为真实地再现振动环境,对振动试验中所需各种激励信号源的要求也就越来越
I. INTRODUCTION Vibration tests used to check the correctness of dynamic analysis results, verify and adjust mathematical models and to verify the overall design are reasonable. With the continuous improvement of test equipment, analytical methods and analytical tools, the vibration tests developed rapidly in recent years. Due to the application of electronic computer in the vibration test, the process control, data analysis and automation in the test process in the vibration test are being perfected. In order to truly reproduce the vibration environment, the requirements for various excitation signal sources required in the vibration test are also increasing
