Abstract
A tunable mass damper is provided. The tunable mass damper includes a mounting bracket and a molded assembly, the molded assembly comprising an elastomeric coating that is overmolded onto a damper mass. The elastomeric coating includes one or more slots that are shaped to receive a corresponding elastomeric tab. Each elastomeric tab can be positioned within a corresponding slot on an as-needed basis to incrementally raise the natural frequency of the tunable mass damper. The molded assembly is then press-fit into the mounting bracket, thereby ensuring the tunable mass damper attenuates engine vibrations at a target frequency.
Claims20
A tunable mass damper comprising:
- a mounting bracket;
- and
- a molded assembly that is press-fit into the mounting bracket, the molded assembly including an elastomeric coating that is overmolded onto a damper mass, wherein the molded assembly further includes an elastomeric tab that is selectively inserted into a slot in the elastomeric coating to increase a natural frequency of the tunable mass damper.
A tunable mass damper comprising:
- a molded assembly including a damper mass that is at least partially encapsulated with an elastomeric coating;
- and
- a mounting bracket having a mounting collar extending around the molded assembly, such that the elastomeric coating is between the damper mass and the mounting collar;
- wherein the molded assembly is adjustably tuned to have a desired natural frequency by selectively inserting an elastomeric tab into a recessed slot in the elastomeric coating.
A molded assembly for a tunable mass damper, the molded assembly comprising:
- a damper mass;
- an elastomeric coating;
- and
- an elastomeric tab that is configured to be received within a slot in an exterior surface of the elastomeric coating for achieving a desired natural frequency of the molded assembly.
