Research on Theoretical Modeling and Parameter Sensitivity of a Single-Rod Double-Cylinder and Double-Coil Magnetorheological Damper

Figure 6

Hydraulic model of the MR damper. D represents the piston diameter (m), l represents the length (m) of one side of the damping channel, h represents the clearance (m) of the damping channel, R_m1 and R_m2, respectively, represent the fluid resistance (N·s/m⁵) in the upper and lower damping channels, I_m1 and I_m2, respectively, represent the fluid inductance (N·s²/m⁵) in upper and lower damping channels, represents volume compliance of the nitrogen gas chamber (m⁵/N), and F represents damping force of the damper (N).
