This paper presents control characteristic of an impact isolator featuring a magneto-rheological elastomer isolator device (MREID). The developed MREID is analysed in term of its magnetic intensity to produce a large of MR effect that controlled by the input current. In order to control the input current, the hybrid skyhook active force control (HySAFC) is proposed. The HySAFC is used to track the signal based on the force obtained from the feedback of the force sensor and accelerometer. However, the control output of the HySAFC is desired force of the current generator which is designed using the inverse adaptive neuro-fuzzy inference system (ANFIS). Then, the selection of the input current using the IF–THEN rules depend on desired force and impact energy for current generator. Next, for the development of control structure, the impact isolation system is formulated and the impact isolation test rig is used to perform the experimental validation process. The validation assessment of HySAFC is experimentally realized, and the control responses, namely such as jerk, accelerations and transmitted forces as well as the impact isolation system are presented in the time domain. Finding of this study, the HySAFC is able to improve the MREID performance for impact loading application in simulation and experiment and capable in providing fast response when impact occurred.

使用磁流变弹性体隔离器的混合式天钩主动力控制,用于减轻冲击

本文介绍了具有磁流变弹性体隔离装置(MREID)的冲击隔离器的控制特性。对已开发的MREID的磁强度进行分析,以产生受输入电流控制的大MR效应。为了控制输入电流,提出了混合式天钩主动力控制(HySAFC)。HySAFC用于根据从力传感器和加速度计的反馈获得的力来跟踪信号。但是,HySAFC的控制输出是电流产生器的期望力,该力是使用逆自适应神经模糊推理系统(ANFIS)设计的。然后,使用IF–THEN规则选择输入电流取决于所需的力和电流发生器的冲击能量。接下来,为了开发控制结构,制定了冲击隔离系统,并使用冲击隔离测试台进行了实验验证过程。通过实验实现了对HySAFC的有效性评估,并在时域内给出了控制响应,如加速度,加速度和传递力以及冲击隔离系统。这项研究的发现,HySAFC能够提高MREID在模拟和实验中的冲击载荷应用中的性能,并能够在发生冲击时提供快速响应。加速度和传递的力以及冲击隔离系统在时域中显示。这项研究的发现,HySAFC能够提高MREID在模拟和实验中的冲击载荷应用中的性能,并能够在发生冲击时提供快速响应。加速度和传递的力以及冲击隔离系统在时域中显示。这项研究的发现,HySAFC能够提高MREID在模拟和实验中的冲击载荷应用中的性能,并能够在发生冲击时提供快速响应。
