摘　　要：文章研究了多轴随机振动试验控制技术,详细阐述了系统传递函数辨识、驱动信号生成、控制修正算法等关键技术。介绍了自主研发的多轴随机振动控制系统的整体架构。利用该系统在三轴振动试验台上开展了多轴随机振动控制试验。试验结果表明采用的控制修正算法可行,控制效果良好,若干关键技术在多轴随机振动控制系统中的控制效果得到验证。This paper analyzes several key aspects of the multi-axis random vibration test control techniquesincluding the identification of the system frequency response function, the generation of the drive signal, and the controlalgorithm. A multi-axis random vibration controller is developed based on those key techniques and the majorframework of the controller is discussed. Finally, a triaxial test is carried out by the controller. The test results show thefeasibility of the control algorithm and the good control strategy of the multi-axis random vibration controller, in whichseveral key techniques are validated.
