摘要
As a newly proposed two-terminal mechanical element, there are many realizations of inerter such as ball-screw, rack and pinion,hydraulic, fluid and mechatronic inerter. This paper concerns about a novel mechatronic inerter, which is consisted of a hydraulic piston inerter and linear motor, called hydraulic electric inerter(HEI). Firstly, the structural components and the working principles of two types HEI device are introduced, and the dynamic model of the HEI is established. Then, three classifications of mechatronic inerter, namely, the single motor type, the linear inerter-motor type and the rotary inerter-motor type are presented,and in the meanwhile, some comparisons among the three types mechatronic inerter are analyzed. Subsequently, a methodology of designing and experimental tests of the HEI device is proposed by considering the rated working conditions of the linear motor and the electric elements. At last, the HEI device is conducted, and the force tests of the non-loaded HEI and loaded HEI are tested in order to validate their properties. The experimental results are analyzed, and the discrepancies are also further discussed.
