| Abstract: | For the problem that ordinary MR damper requires extra field coil and has dependence on energy with large volume and complex structure,a magnetic field structure of passive adaptive MR damper was designed.The magnetic circuit provided magnetic field by permanent magnet and transformed the variation of load force on MR damper into the variation of relative permeability of giant magnetostrictive material based on giant magnetostrictive inverse effect,and thus made magnetic field through the magnetorheological... |
