Magnetorheological Fluid Compositions

US Patent:
7419616, Sep 2, 2008
Filed:
Aug 11, 2005
Appl. No.:
11/202414
Inventors:
John C. Ulicny - Oxford MI, US
Mark A. Golden - Washington MI, US
Keith S. Snavely - Sterling Heights MI, US
Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
H01F 1/44
US Classification:
252 6252
Abstract:
A magnetorheological fluid composition comprising a carrier fluid; and a plurality of high aspect ratio magnetizable particles, wherein the aspect ratio of the high aspect ratio magnetizable particles is greater than 1. 5. Optionally, the high aspect ratio magnetizable particles can have interlocking structures comprising male component and a female component. Still further, a magnetorheological fluid composition can comprise low aspect ratio magnetizable particles having the interlocking structures, wherein the aspect ratio of the low aspect ratio magnetizable particles is 1 to 1. 5.

US Patent:
7878387, Feb 1, 2011
Filed:
May 7, 2009
Appl. No.:
12/436851
Inventors:
John C. Ulicny - Oxford MI, US
Paul E. Krajewski - Troy MI, US
Mark A. Golden - Washington MI, US
Keith S. Snavely - Sterling Heights MI, US
Assignee:
GM Global Technology Operations LLC - Detroit MI
International Classification:
B21K 31/02
US Classification:
228256, 228246, 2282481

Iron Powder Phosphonate Coating

US Patent:
8226845, Jul 24, 2012
Filed:
Oct 27, 2008
Appl. No.:
12/259188
Inventors:
Andrew M. Mance - Royal Oak MI, US
Keith S. Snavely - Sterling Heights MI, US
Mark A. Golden - Washington MI, US
John C. Ulicny - Oxford MI, US
Assignee:
GM Global Technology Operations LLC - Detroit MI
International Classification:
C01G 49/08
H01F 1/00
US Classification:
252 6256, 252 6253
Abstract:
A fluid includes a liquid medium having iron particles mixed therein. An organic phosphonate based coating is established on the iron particles. The organic phosphonate based coating does not substantially include phosphonic acid groups at an outer surface thereof, and increases oxidation resistance of the iron particles. A method of making such a liquid medium is also disclosed herein.

Magnetorheological Compositions Including Nonmagnetic Material

US Patent:
8361341, Jan 29, 2013
Filed:
Oct 9, 2009
Appl. No.:
12/576485
Inventors:
John C. Ulicny - Oxford MI, US
Mark A. Golden - Washington MI, US
Keith S. Snavely - Sterling Heights MI, US
Prabhakar Marur - Karnataka, IN
Assignee:
GM Global Technology Operations LLC - Detroit MI
International Classification:
H01F 1/44
US Classification:
252 6252, 252 6255
Abstract:
A magnetorheological composition includes a mixture of a carrier medium and a particle component disposed in the carrier medium. The particle component includes a magnetic material and a nonmagnetic material. The nonmagnetic material is present in the particle component in an amount of from about 5 to about 95 parts by volume based on 100 parts by volume of the particle component. The particle component is present in the magnetorheological composition in an amount of from about 20 to about 80 parts by volume based on 100 parts by volume of the magnetorheological composition. The magnetorheological composition has an on-state yield stress at magnetic saturation of from about 0. 1 to about 100 kPa.

Localized Impact Energy Absorbers

US Patent:
8485588, Jul 16, 2013
Filed:
May 11, 2012
Appl. No.:
13/469241
Inventors:
Mark A. Voss - Richmond MI, US
Paul E. Krajewski - Troy MI, US
Keith S. Snavely - Sterling Heights MI, US
Matthew F. Pawlicki - Williamsville NY, US
Assignee:
GM Global Technology Operations LLC - Detroit MI
International Classification:
B62D 25/10
US Classification:
29618704, 29619311, 180 6922, 180 692
Abstract:
A vehicle hood or a panel covering an object includes an inner surface and an outer surface. The inner surface faces the object and is offset from the object by a basin depth. The outer surface is substantially opposite the inner surface. A local energy absorber is operatively attached to the inner surface or is disposed between the inner surface and the object. The local energy absorber has a singly-connected structure, which includes a first wall portion and a second wall portion. The first wall portion is operatively attached to the inner surface. The singly-connected structure also includes a curved connector portion joining the first wall portion and the second wall portion.

Magnetorheological Fluids

US Patent:
2003003, Feb 13, 2003
Filed:
Aug 6, 2001

John Ulicny - Oxford MI, US
Keith Snavely - Sterling Heights MI, US
Anthony Smith - Troy MI, US
International Classification:
H01F001/28
US Classification:
252/062520
Abstract:
One embodiment of the invention includes an MR fluid of improved durability. The MR fluid is particularly useful in devices that subject the fluid to substantial centrifugal forces, such as large fan clutches. A particular embodiment includes a magnetorheological fluid including 10 to 14 wt % of a hydrocarbon-based liquid, 86 to 90 wt % of bimodal magnetizable particles, and 0.05 to 0.5 wt % fumed silica.
