The paper presents numerical analysis of an absorber/harvester system installed on the semi‐active suspension. The pendulum tuned mass absorber has been modified by use of a magnetic levitation harvester. The primary goal is to mitigate the vibration of the primary structure and the secondary goal is to harvest energy out of the vibration absorber simultaneously. This system is strongly nonlinear and the unstable regions are detected. Therefore, to control the dynamic response the semi‐active suspension consisting of the magnetorheological (MR) damper and the shape memory alloy (SMA) spring is proposed. It is shown that with a proper configurations of parameters an effective energy harvesting can be obtained combined with vibration mitigation in the host system.

具有半主动悬架的摆式减振器/收割机系统的数值研究

本文介绍了安装在半主动悬架上的吸收器/收割系统的数值分析。摆调谐质量吸收器已通过使用磁悬浮收集器进行了修改。主要目标是减轻主要结构的振动，而次要目标是同时从减振器中收集能量。该系统是强非线性的，可以检测到不稳定区域。因此，为了控制动态响应，提出了一种由磁流变（MR）阻尼器和形状记忆合金（SMA）弹簧组成的半主动悬架。结果表明，通过适当配置参数，可以结合主机系统中的减振功能获得有效的能量收集。
