Hydraulic hybrid vehicle vibration isolation control with magnetorheological fluid mounts

摘要: Hydraulic Hybrid Vehicle (HHV) is an emerging technology especially for heavy-duty vehicles, thanks to its high efficiency and power density. However, one of the main problems that should be solved enable successful commercialisation HHV excessive noise vibration involved with hydraulic systems. This study focuses on using magnetorheological fluid (MRF) reduce transmissibility from sources vehicle body. To HHVs, a structure in parallel design was analysed. An MRF mount, use engine pump/motor, designed, fabricated tested. Vibration control schemes based skyhook algorithm were utilised amplitudes vibration. The research showed mounts played important role reducing transmitted Additionally, locations orientations isolation system affected mitigation.
