Abstract: The magneto-rheological damper (MRD)
has been widely explored in the study of vibration suppression for vehicle
suspension and constructional systems, which includes strong nonlinearities
arisen from the semi-active control strategy, road surface shock
excitations, high-frequency devices in control circuit. Due to the
displacement vibration and semi-active control strategy, radiated emission
are produced through the cable and excitation coil based on the semi-active
control signal. To solve the problem, the radiated emission mechanism and
models are proposed and analyzed. Moreover, a novel smoothing algorithm is
designed to mitigate the above radiated emission. The simulation and
experiment results show that radiated emission can be suppressed 2-4 dBμ
V/m by employing the present smoothing algorithm and comply with EN 55022,
which will play an important role in future application study for the
electromagnetic interference reduction of intelligent vehicle suspension
design with MRDs.
