电液伺服振动台的动力学特性制约着其控制精度的提高，其动力学特性分析方法以及非线性补偿、控制研究一直是该领域的热点。概述了电液伺服振动台动力学研究的现状，内容包括动力学建模方法、动力学方程中的非线性因素以及动力学特性仿真分析等。对于建立的动力学模型，既能真实、全面地反映液压振动系统的实际性能，又能快速、精确求解是研究的关键所在；对于电液伺服振动台动力学特性仿真，目前较为普遍的研究思路是基于接口的多平台联合仿真，但基于统一语言和统一平台的多学科建模与仿真技术正在兴起并可以更好地对电液伺服振动系统的动力学特性进行仿真分析。并展望了存在的一些问题，对值得关注的研究提出了自己的看法。

Electro-hydraulic servo shaking table’s dynamic performance restricts the enhancement and improvement of its control precision. Analytic methods of dynamic performance,nonlinear compensation and control methods of hydraulic shaking table have be-come the emphases of current research. The recent research advances of electro-hydraulic shaking table’s dynamics in modeling meth-ods,nonlinear properties,and numerical simulation were reviewed. A dynamic model that could not only describe a hydraulic system roundly and factually but also be numerical calculated precisely and time-saving was sticking point of current research. At present,the research thinking of dynamic numerical simulation for hydraulic servo system was basically focused on joint modeling and co-simulation employing at least two kinds of simulation software. However,multidisciplinary modeling and simulation based on unified language and platform was rising and gradually becoming developing trend. Finally,a number of open problems were reviewed and a few prospective research topics in a near future were suggested.
