Comfort　of　the　vibratory　road　roller　is　an　important　research　title.　A　2-DOF　non-line　model　is　set　up,　which　is　more　close　to　the　actual　situation　of　the　vibratory　road　roller.　A　simulation　using　MATLAB/SIMULINK　is　carried　out　to　validate　this　model　and　study　its　dynamic　characteristic　and　analyze　the　motion　laws　of　its　housing　and　wheel.　A　kind　of　Magneto-rheological　(MR)　damper　is　designed　which　has　been　widely　used　in　automotive　and　bridge　damping　in　recent　years,　and　applied　to　a　vibratory　road　roller　to　control　it.　The　control　strategy　uses　fuzzy　control.　The　results　indicate　that　the　damping　performance　of　the　vibratory　road　roller　which　applied　MR　damper　is　improved　remarkably.　©　(2012)　Trans　Tech　Publications.
