摘要： A hollow beam structure such as a machinery subbase having apertures in sidewall portions thereof has a plurality of shear damper assemblies which straddle the apertures and are fastened to the wall portion on opposite sides of the apertures. The shear damper assemblies include a viscoelectric damping layer which dissipates vibrational energy to minimize the vibrational response of the hollow beam structure.

摘要： A casting apparatus for casting a railcar coupler, which includes a shank portion and a head portion, includes cope and drag portions that define an external shape of the coupler. The casting apparatus also includes one or more cores that define an interior of the shank portion and a separate head core with an exterior that defines an interior of the head portion that includes lock chamber, guard arm side portion, and knuckle side portions of the head. The head core is a single piece with a hollow center section that defines a front face gating system that includes at least one in-gate configured to direct molten material to top and bottom regions of the head to define the lock chamber, guard arm side portion, and knuckle side of the head.

摘要： A main body core box assembly for creating coupler head cores which are attachable to various shank cores includes a main body core box including two halves, each half including a pattern configured to form the outer walls of a first head core having a first shank core. A plug is insertable into an end of respective patterns to form a second, alternative head core having a first half of a connection joint attachable to a second shank core that includes a second half of the connection joint, the second shank core being different than the first shank core. The first half of the connection joint may be a male connector, where the plug includes a recess having an angled surface to create a notch on the male connector. The second half of the connection joint may be a female connector with a raised surface corresponding to the notch.

摘要： A railroad coupler knuckle includes a single, solid rib at a horizontal centerline of the knuckle that passes through a pivot pin hub thereof. The single, solid rib extends generally from a flag hole of a finger cavity of the knuckle to an opposite side of the knuckle from the flag hole. In another aspect, a railcar coupler knuckle includes a tail section, a hub section, and a nose section. The tail, hub, and nose sections define internal cavities including (i) a combined void that defines a pivot pin hub cavity and a kidney cavity and (ii) an isolated finger cavity. The combined void is formed using a first internal core during manufacturing of the coupler knuckle. The isolated finger cavity is formed using a second internal core during manufacturing of the coupler knuckle, such that molten alloy substantially separates the combined void and the isolated finger cavity.

摘要： A method for manufacturing a railcar coupler knuckle, said method includes providing a cope mold portion and a drag mold portion. The cope and drag mold portions have internal walls that define at least in part perimeter boundaries of a coupler knuckle mold cavity. At least one chill core is positioned within one of the cope mold portion and the drag mold portion. The cope and drag mold portions are closed, with the at least one core therebetween, and the closed cope and drag mold portions and the chill core define a parting line. The mold cavity is filled with a molten metal, which solidifies after filling to form a casting. The casting includes a pulling face portion defined by the chill core, and a central section of the pulling face portion does not contain the parting line and requires no finish grinding upon its formation.
