摘要： An MR fluid formulation comprising water-atomized iron powder dispersed in a liquid vehicle, wherein the atomized iron powder contributes to a higher magnetic effect, a lower viscosity and suitability for high temperature applications. The magnetizable particles are prepared by controlled water atomization and comprise iron having a passivating oxide surface layer. The passivating oxide surface layer advantageously comprises iron oxide and at least one alloying metal oxide, such as manganese oxide. Advantageously, the particles have a grain size of at least 4 &mgr;m and a mean diameter in the range of about 8-25 &mgr;m. The liquid vehicle advantageously comprises a mixture of at least two liquid components of different surface functionality and an organoclay stabilization mixture in which at least one organoclay is selected for each liquid vehicle component. Exemplary MR fluid formulations of the present invention utilize a high-viscosity, low volatility base fluid, water-atomized iron powder, multi-component organoclays and multi-component additives to achieve the desired viscosity and durability of a fully formulated MR fluid which will satisfy the requirements of second and third generation MR fluids.

摘要： 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.

摘要： A method has been developed to use a structural epoxy adhesive to bond together surfaces of phosphated steel electrodeposited with an organic primer. The specially formulated epoxy adhesive contains a cross-linkable epoxy novolac resin, an epoxy reactive diluent, and an imidazole curing agent substituted in at least one position with an alkyl or a hydroxyalkyl group. The amount of the curing agent used in the formulation is much lower than that in a conventional two-part epoxy adhesive such that the adhesive will not attack or degrade the primer layer to weaken the bond strength. The reactive diluent used reduces the viscosity of the mixed adhesive system to facilitate dispersion and wetting of the adhesive on the coated steel surface. Bond strength achieved by this method is adequate for automotive structural applications and is capable of withstanding extended exposure to humidity, salt spray, and other hostile automotive environments without appreciable loss.
摘要翻译：已经开发了一种使用结构环氧粘合剂将电沉积有机底漆的磷酸盐钢的表面粘合在一起的方法。特殊配制的环氧粘合剂含有可交联的环氧酚醛清漆树脂，环氧反应性稀释剂和在至少一个位置被烷基或羟烷基取代的咪唑固化剂。制剂中使用的固化剂的量远低于常规的两部分环氧粘合剂中的固化剂的量，使得粘合剂不会侵蚀或降解底漆层以减弱粘合强度。使用的反应性稀释剂降低了混合粘合剂体系的粘度，以便于在涂覆钢表面上的粘合剂的分散和润湿。通过这种方法实现的粘合强度足以用于汽车结构应用，并且能够耐受长期暴露在湿度，盐雾和其他恶劣的汽车环境中，而没有明显的损失。

摘要： A magneto-rheological damping assembly including a piston (28) defining a core (38). A pair of spaced electromagnets (46) are disposed about the core (38) and are connected to a controller (48) for selectively generating a magnetic flux. A pair of permanent magnets (52) are disposed about the electromagnets (46) and a pole segment (54;154;56;156) is disposed therebetween. A main gap (74) extends through the piston (28) through which magneto-rheological fluid (26) is conveyed. Flux generated by the magnets controls the viscosity of the fluid in the main gap (74) to control the damping force of the assembly. The controller (48) defines an off operating state for cancelling the flux from the permanent magnets (52) across the main gap (74). The core (38) and the pole segment (54;154;56;156) define a closed auxiliary gap (80) extending axially between the electromagnets (46) and radially between the core (38) and the internal pole segment (56) for preventing leakage of flux across the main gap (74) when the assembly is in the off operating state.
