Abstract
Aiming at the problem of limited application caused by insufficient effective working length of traditional Magnetorheological Damper (MRD), this paper proposed a new full-channel effective MRD with trapezoidal section magnetic conducting ring. On the basis of the quasi-static analysis of the traditional magnetorheological damper, the new quasi-static is analyzed by using the Takagi-Sugeno fuzzy neural network model and the principle of magnetic circuit design. Four full-channel effective MRDS with different structures were compared by finite element simulation and the proposed quasi-static was verified according to the experimental results of damping characteristic. The results show that the new full-channel effective MRD can significantly improve the effective working length of the damping channel and effectively improve the magnetic saturation problem, Under the same current excitation, the magnetic field intensity distribution of the damping channel is more uniform, the average magnetic field intensity is larger, and the output damping force is larger. The error between the quasi-static analysis and the experimental results of the damping characteristics of the full-channel effective MRD with trapezoidal section magnetic conducting ring is smaller than that of the traditional quasi-static analysis. The proposed quasi-static can be effectively applied to the structural design of both traditional and new full-channel effective MRDs.
