Abstract
A vibration damping component for a vehicle includes a housing, and a mounting lug attached to the housing. The mounting lug includes an outer shell with a top, a bottom, and sides. The mounting lug also includes a bore through the outer shell from the top to the bottom. The mounting lug also includes a cavity, an interior lattice, and a damping media. The outer shell and the bore enclose the cavity. The interior lattice is within the cavity and stiffens the mounting lug. The damping media is enclosed in the cavity and between solid portions of the interior lattice.
Claims9
A method of additively manufacturing a vehicular component with a mounting lug having vibrational damping media (34),
- the method comprising:
- Additively manufacturing the component including a housing (14) and the mounting lug (12),
- wherein additively manufacturing the mounting lug (12) includes encasing a powder in an outer shell of the mounting lug (12);
- heating the component to densify solid portions of the component while maintaining the granular structure of the build powder encased in the mounting lug (12);
- and
- finishing a surface of the component.
