This paper proposes a vibration control-energy harvesting damper (VCEHD) for vehicle suspension. The principles used in the proposed VCEHD include quasi-zero stiffness (QZS), mechanical motion rectifier (MMR), and semi-active control. In the dynamic analysis, the authors found that the inherent disengagement and engagement properties of the MMR can undermine the robustness of the system, that is, the inherent properties of the MMR as an energy harvesting device are not conducive to vibration isolation. Therefore, it needs to be restrained. According to the numerical simulation results, VCEHD cannot simultaneously achieve the minimum body displacement and the maximum energy harvest, and the energy harvest performance needs to be partially sacrificed. The experimental results show that the maximum energy output is 14.70 mW/kg, and the minimum displacement transmissibility is 24.32%. Combined with the numerical simulation results, VCEHD can harvest 8.82–97.79 W of power in actual vehicle running, which can provide auxiliary power for intelligent vehicles.

可持续性和阻尼的关系：用于车辆悬架的准零刚度和伪分段惯性阻尼器

本文提出了一种用于车辆悬架的振动控制能量收集阻尼器（VCEHD）。所提出的 VCEHD 中使用的原理包括准零刚度 (QZS)、机械运动整流器 (MMR) 和半主动控制。在动态分析中，作者发现MMR固有的脱离和接合特性会破坏系统的鲁棒性，即MMR作为能量收集装置的固有特性不利于隔振。因此，需要对其进行抑制。根据数值模拟结果，VCEHD无法同时实现最小的身体位移和最大的能量收集，并且需要部分牺牲能量收集性能。实验结果表明，最大能量输出为14.70 mW/kg，最小位移传递率为24.32%。结合数值模拟结果，VCEHD在车辆实际行驶中可收获8.82~97.79 W的功率，可为智能车辆提供辅助动力。
