The traditional damping structure usually transfers the vibration energy into heat, dissipated and without harvesting. But for harsh environments, such as military activities and lunar probe patrols, the vibration energy can be extracted, and realize the purpose of self-power condition monitoring. In this paper, a bionic suspension with energy-harvesting property is proposed based on bionic configurations. The bionic suspension adopts a symmetrical three-link arrangement to simulate the arrangement of bones, and a horizontal spring to simulate muscles. The micro-generator embedded in the knee joint provides the main damping force for the overall structure and also plays a role in harvesting energy. The dynamic equation and virtual prototype model are established, and the effects of parameter changes on the performance of vibration reduction and energy harvesting are analyzed, and the relationship between the two is revealed. The results show that the parameters to achieve their respective optimal performance are not consistent in the trend, though it is difficult to obtain the best performance of both, it can be designed according to the specific functions to be satisfied. This structure can be utilized as a general model for vibration reduction and energy harvesting scenarios, providing new ideas for self-powered sensing and condition monitoring configurations.

传统的阻尼结构通常将振动能量转化为热量，耗散且不收集。但对于恶劣环境，如军事活动、月球探测器巡视等，可以提取振动能量，实现自供电状态监测的目的。本文提出了一种基于仿生构型的具有能量收集特性的仿生悬架。仿生悬架采用对称三连杆布置来模拟骨骼的布置，并采用水平弹簧来模拟肌肉。嵌入膝关节的微型发电机为整体结构提供主要阻尼力，同时也起到能量收集的作用。建立了动力学方程和虚拟样机模型，分析了参数变化对减振和能量收集性能的影响，揭示了两者之间的关系。结果表明，实现各自最优性能的参数在趋势上并不一致，虽然很难获得两者的最优性能，但可以根据具体功能进行设计以满足需要。该结构可用作减振和能量收集场景的通用模型，为自供电传感和状态监测配置提供新思路。
