Summary:A hydraulic mount for an automotive vehicle or machine includes opposed mounting members secured to an elastomeric body and a base, respectively. An orifice plate assembly is interposed the body and the base to define a pumping chamber and a reservoir for fluid to flow therebetween through an orifice track of the orifice plate assembly. An electroactive polymer decoupler member is secured in a cavity formed between two orifice plates of the orifice plate assembly. The decoupler member is operably connected to a controller for imposing an electric field on the decoupler member to change its shape and thereby selectively vary the dynamic stiffness of the mount.
