Modeling and Experimental Study on Adjustable Magneto-rheological Fluid Damper Based on Hydro-pneumatic Suspension of Heavy Vehicles
In this paper, the structure and working principle of a new adjustable MRF damper are presented for hydropneumatic suspension system of heavy wheeled vehicle. According to the characteristic design, disc radial orifice valve is developed to meet the adjustable and fail-safe requirements. After its describing the process of compression and rebound strokes of this device, Non-linear mathematic models are created and adopted to perform the damping force analysis. In addition, an experimental setup on a 200 kN servohydraulic testing machine is constructed to test the damping characteristics under different velocities and control currents with a sinusoidal excitation. These tests demonstrate that this new device can offer good performance for the improvement of ride quality and stability in a semi-active suspension.
