摘要：Energy-saving and low-carbon technology for vehicles is a research hotspot. Considering the large power dissipation in suspension system, a hybrid electromagnetic energy-suspension suspension damper is proposed based on Halbach permanent magnet array. The eddy current generation structure and an electromagnetic energy harvesting device are combined, and the relationship between feed energy damping performance and eddy current damper is studied. The equivalent magnetic circuit model of the electromagnetic energy harvesting device is established. The dislocation rate between the two sets of permanent magnets is defined. The influence of the dislocation rate on the output electrical performance of the composite damper and the eddy current loss of the eddy current structure is analyzed. Finally, the prototype and a corresponding damping test platform are built. The damping coefficient adjustment range of the prototype can be widened from 500 to 1 270 N•s/m, and the maximum energy harvesting power can be up to about 1.7 W at a dislocation rate of γ=1 (Simple harmonic excitation with frequency f=5 Hz and amplitude Y=6 mm). The maximum specific mass damping coefficient can reach 1 427.0 s-1. The hybrid electromagnetic regenerative suspension damper provides a new idea for future research on suspension energy recovery and electromagnetic damper design. © 2019, Science Press.
