摘　　要：该文介绍了国内外多自由度振动台的主要应用领域、需求状况和发展趋势;对超大规模多自由度振动台的并联机构进行运动学、动力学分析;分析了振动台台体的自振频率与加速度响应一致性之间的关系,介绍了振动台台体设计的基本原则,最后从自由度合成与分解、运动学分析、同步控制三个方面分析了超大规模多自由度振动台的控制方法。In this paper, we introduce the main application fields, requirements and the development tendency of the Muhi-DOF （degree of freedom） shaker and then analyze the kinematics and dynamics of the parallel mechanism of the super-large scale Multi-DOF shaker. The relationship between the natural frequency of the shaker and the consis-tency of the acceleration response is studied. Then the basic principle of the shaking table design is presented. In the end of this paper, the control method of the super-large scale Muhi-DOF shaker is analyzed based on three aspects： the composition and decomposition of the degree of freedom, the kinematics analysis and the synchronous control.
