摘　　要：在建立磁流变弹性体隔振缓冲器动力学模型的基础上,提出一种基于仿人智能控制理论的控制策略。它将隔振缓冲器的工作状态划分为6个特征模态,对不同的特征模态采取不同的控制模态。仿真结果表明,仿人智能控制与传统的离复位模糊控制相比,能很好地控制上质量块即仿冲物体的加速度最大峰值和两质量块的相对位移,有效地改善了隔振缓冲器的隔振缓冲性能。A dynamic model of MRE isolation-buffer was built, and human-simulated intelligent control (HSIC) was presented. Working state of isolation-buffer was divided into six characteristic modes, and a corresponding control mode was selected according to different characteristic modes. Simulation results show that HSIC, compared with traditional off-and-towards-equilibrium fuzzy control, can well control maximal peak of acceleration in up mass-block and relative displacement between two mass-blocks, and effectively improves the performance of the isolation-buffer.
