bunnstøt

Bunnstøt is a Norwegian compound noun formed from bunn meaning bottom and støt meaning support or stop. In technical usage, it refers to a point, device, or feature that prevents further downward movement or contact with the base of a system, effectively acting as a bottom stop or base contact.

In mechanical engineering and machinery, bunnstøt can describe either a structural contact at the bottom of a stroke or a dedicated component that cushions impact when the moving part reaches the end of its travel. Common implementations include rubber bumpers, pads, or metal stops designed to absorb energy, reduce vibration, and protect components from damage.

In vehicle suspension and related systems, the term is often used to describe the bottoming-out point of travel. This includes bump stops or travel limiters that prevent the suspension from compressing beyond its designed range, thereby mitigating harsh impacts and wear.

In construction or architecture, bunnstøt may refer to a base support or foundation element that prevents excessive settlement or movement of a structural member, or to load-distributing pads placed at the bottom of a component.

Etymology and usage notes: the term is primarily used in Norwegian technical language, with occasional translations or adaptations in bilingual texts. English-speaking engineers may use equivalents such as bottoming-out point, bottom stop, travel limiter, or bumper depending on the context.
