reduction of vibration - Opis:
- Low speeds of mobile heavy machines makes that the force derived from rough roads cause intense excitation of low frequency vibration, the reduction of which is possible only by active or semi active methods. In conditions of low frequency, the energy dissipation in the tire reduces the vibration intensity in a minor degree only magnetorheological dampers are free from this defect, which they properties changing under influence an electric field functioning on ferromagnetic particles of oil suspension. A controlling coil current, which is mounted in the damper piston, could control density of magnetic field lines (magnetic field intensity) directly in viscous hole of piston, and hence viscous drag force. Electric energy needed to control magnetorheological damper is generally available in each of mobile heavy machines. Simulation tests were performed to investigate effectiveness and stability of the proposed solution and the results were deemed satisfactory. The system was found to be feasible and implementable with respect to every parameter. The purpose of this study was to develop a simulation model of the semi active suspensions of operator’s seat based on magnetorheological damper, and to examine the effectiveness of using different control strategies.
