Abstract: A tuned mass damper includes a damper mass having a first mass portion and a second mass portion connected by a third mass portion. The first mass portion, the second mass portion, and the third mass portion form a U-shaped configuration of the damper mass. The damper mass is configured to separate within the third mass portion in response to a force transferred to the damper mass of the tuned mass damper to allow relative motion between the first mass portion and the second mass portion. The damper mass may include geometric features that promote rotation of the tuned mass damper relative to an axis, when subjected to impact loads.

Abstract: A battery pack includes an enclosure defining an enclosure interior, a stack of battery cells disposed in the enclosure interior between a first wall of the enclosure and a second wall of the enclosure, and a side beam extending from the first wall to the second wall and adjacent to the stack of battery cells. The side beam includes a plurality of interconnected elements forming a web, where a portion of the web is configured to collapse in response to a force against a side of the battery pack exceeding a threshold force.
