摘　　要：发射阶段经受的恶劣振动环境,往往造成卫星发射失败。为了改善卫星在发射阶段的振动环境,提出了一种基于磁流变技术的星箭界面半主动隔振平台,用来替换传统的用于星箭连接的锥壳适配器。分析了布置参数、刚度系数、阻尼特性等主要特性参数对隔振平台传递特性的影响。搭建了星箭界面隔振实验平台,采用天棚阻尼控制策略,对隔振平台进行半主动控制。利用正弦扫频激励完成了模拟实验,实验结果表明:隔振平台原理可行、主要特性参数可调、隔振效果良好。The harsh vibration environment experienced in the launch phase often lead the satellites to the failure of launch. In order to improve the vibration environment for the satellites, a semi active vibration isolation platform using magnetorheological technology is designed. It would be expected to replace the traditional conical shell adapterused to connect the satellite and the rocket. The influence of layout parameters, i.e. the stiffness and damping on the isolation platform＇s transmission charac teristics is analyzed. Then the experimental platform is set up, which is controlled by a semi-active control method named Sky- hook. Simulation experiment was done through sweeping sine excitation and the experimental results show that the principle of the platform is feasible, the main characteristics parameters are adjustable and the effect of vibration isolation is good.
