摘要
针对常规磁流变阻尼器功能单一且能量采集效率低下的不足,提出并设计了一种集阻尼力可控、位移自感应和振动能量采集多功能于一体的位移自感应振动能量采集型磁流变阻尼器。介绍了所设计的阻尼器工作原理及位移自感应工作特性。采用ANSYS有限元仿真软件对处于不同工作位置的位移自感应装置进行电磁耦合仿真,得到自感应电压随活塞头相对位置的分布关系。加工制造出样机并搭建实验测试系统,测试分析了该磁流变阻尼器的动态位移自感应性能。测试结果表明:自感应电压幅值随着位移激励幅值的增大而线性增大,且其线性灵敏度达到54.37 mV/mm。
A novel magnetorheological(MR)damper integrated with controllable damping,displacement self-inducing and energy harvesting ability is developed to solve the problems of simple function integration and low efficiency of vibration energy harvesting in conventional MR damper systems.The working principle of the proposed MR damper is analyzed,especially the principle of displacement self-induced device is explained in detail.The displacement self-induced device at different displacement position is simulated by ANSYS software,and the distribution relationship between the self-induced voltage and displacement of the piston head is obtained.The prototype of the proposed MR damper is manufactured and the experimental test system is set up.The experimental results show that the self-induced voltage amplitude increases linearly with the increase of the amplitude of sinusoidal displacement excitation,with a displacement sensitivity of up to 54.37 mV/mm.
