VIBRATION-DAMPED PRECISION CAST ALUMINUM ALLOY AUTOMOTIVE MEMBER FOR A VEHICLE POWERTRAIN AND METHOD OF MANUFACTURING THE SAME |
摘要 |
A vibration-damped precision cast aluminum alloy automotive member for a vehicle powertrain and a method of its manufacture are disclosed. The vibration-damped precision cast aluminum alloy automotive member includes an internally disposed aluminum or aluminum alloy insert. An exterior surface of the insert, which includes an exposed oxide film, establishes a non-bonded interface with an interior surface of the automotive powertrain member. This non-bonded interface damps vibration propagation through the automotive powertrain member by experiencing frictional contacting movement when the automotive powertrain member is vibrationally excited.
