Magneto-rheological damper with grooved fluid passages |
摘要 |
Performance of a vehicle damper utilizing a Magneto-Rheological (MR) fluid is enhanced through use of a piston having grooves in the walls of a magnetic flux path portion of a fluid flow passage through the piston. The grooves result in a focusing and intensification of the magnetic flux emanating from the corners of the grooves, to thereby intensify the magnetic flux impressed across the fluid flow passage and cause a greater degree of change in viscosity of the MR fluid flowing through the passage than is achievable in prior MR dampers having smooth-walled fluid flow passages.
