    Abstract: A temperature compensation method for controlling a damping force of a magnetorheological (MR) damper (10) is disclosed. First, a base operating current (IOS1) as a function of a desired force level of a damping force of the MR damper (10) is determined, and a temperature compensation as a function of an operating temperature of the MR damper (10) is determined. Finally, the temperature compensation is applied to the base operating current (IOS1) to generate a compensated operating current (IOS2) as a function of the desired force level of the damping force and the operating temperature of the MR damper (10). To refine the compensated operating current (IOS2), the temperature compensation can be determined as both a function of the operating temperature of the MR damper (10) and a relative velocity of the MR damper (10).

    Abstract: An additives package for use in an MR fluid formulation is provided, as well as an MR fluid formulation containing the additives package. In one embodiment, the additives package comprises an organomolybdenum dithiocarbamate, an ashless dithiocarbamate, and a triazole compound, such as a tolutriazole compound. In another embodiment, the additives package may further include an aminic antioxidant, such as an alkylated diphenylamine. In another embodiment, the additives package is free of an organomolybdate ester. In another embodiment, the additives package consists of the organomolybdenum dithiocarbamate, the ashless dithiocarbamate, the triazole compound, and optionally the aminic antioxidant. In addition to the additives package, the magnetorheological fluid formulation comprises magnetizable particles, a carrier fluid, and a thickening agent.

    Abstract: A magnetorheological fluid formulation comprising magnetizable particles dispersed in a non-aqueous, glycol-based liquid vehicle thickened effectively by either a fully treated fumed silica or an organoclay. The surface treated fumed silica is fully treated with a treatment molecule having a molecular weight of at least about 200. The organoclay comprises sepiolite and/or palygorskite. The glycol-based fluid advantageously consists essentially of propylene glycol and optionally ethylene glycol.

    Abstract: A magnetorheological fluid formulation comprising magnetizable particles dispersed in a multi-component liquid vehicle comprising an organoclay stabilization mixture. At least one organoclay is selected for each liquid vehicle component, each organoclay having a surface chemistry that renders it preferentially compatible with the surface functionality of one of the liquid components relative to its compatibility to the remaining components whereby it is effective to stabilize, or gel, that component. A method of making an MR fluid is also provided in which liquid vehicle components are blended together, the organoclay mixture is added to the blend, and magnetizable particles are suspended therein, resulting in a stable MR fluid of suitable viscosity and yield stress.
