Abstract: A noise vibration harshness reduction assembly includes a housing, a component, and an axial ring. The component is supported via the housing and movable relative to the housing. The axial ring is disposed axially along the component. The axial ring is configured to attenuate axial sound inducing vibrations in response to operation of the component.

Abstract: A sound reduction assembly includes a housing and a component supported via the housing. The component is movable relative to the housing. The sound reduction assembly includes a ring coupled to the component and the housing. The ring is configured to attenuate sound inducing vibrations in response to operation of the component. The ring includes a flange fixed relative to the housing to maintain a position of the ring relative to the component which maximizes attenuation of the sound in response to operation of the component. A method of utilizing a ring to attenuate sound inducing vibrations in response to operation of a component inside of a housing. A torque is selected to be applied to the ring. A stiffness of the ring is determined based on a stiffness-torque curve utilizing the selected torque to maximize attenuation of the sound. The ring is manufactured to meet the determined stiffness.

Abstract: A method of laser welding a steel substrate and a ductile iron substrate is disclosed along with a laser welded assembly that may be formed by practicing the disclosed method. The disclosed laser welding method involves forming a laser weld joint between the steel and ductile iron substrates. The laser weld joint includes a fusion zone comprised of austenite ferrous alloy that has a composition derived from intermixing molten portions of the steel and ductile iron substrates as part of the laser welding process. The austenite ferrous alloy that constitutes the fusion zone of the laser weld joint has a carbon content of 2 wt % or more and a nickel equivalent of 60% or more and can be achieved without preheating the steel and ductile iron substrates prior to welding or using a filler wire to introduce a foreign metal into the molten substrate material created by the laser beam.
