摘　　要：振动台是高层建筑、原子能反应堆、海洋结构工程、桥梁工程等重要设施的抗震性能试验的重要设备。为了提高振动台有效载荷,振动台通常采用液压驱动冗余并联机构。而冗余驱动液压振动台的关键问题在于减小各激振器之间的内力。以16激振器冗余驱动液压振动台为对象,并通过对冗余驱动并联机构内力空间的分解,提出了基于内力空间分解矩阵的内力反馈控制方法。建立了该振动台Simulink仿真模型并进行了仿真,仿真结果验证了该方法的有效性。Seismic shaking table is an important device performance test for high-rise buildings,nuclear reactors,marine structural engineering,bridge engineering and other important facilities. In order to increase the payload shaker,generally redundant parallel hydraulic drive mechanism was used for the shaker. The key problem of redundant driving hydraulic shaking table was to reduce the internal forces between each shaker. By means of the decomposition of the internal force space of a redundant driving parallel mechanism,a method of internal force feedback control was proposed that targeted at the exciter16 unit of the shaker. The establishment of simulation model for the Simulink shaking table and simulation are done,and the simulation results demonstrate the effectiveness of this method.
