Stoppesegenskap

Stoppesegenskap refers to the set of properties of a system, component, or process that determine how quickly and reliably it can be brought to a halt. The term combines stopp and egenskap and is used primarily in Norwegian technical and safety contexts. The concept is applied across fields such as mechanical engineering, electrical engineering, process control, robotics, and transportation, where a controlled and safe shutdown is essential.

Stoppesegenskap encompasses both performance and safety aspects. Key performance metrics commonly considered are stopping time (the interval from initiation of a stop signal to complete halt), stopping distance (or deceleration profile), and the maximum deceleration achievable without compromising safety or integrity. Reliability and fail-safe behavior—ensuring that a stop is executed under fault conditions—are also central. Energy dissipation, mechanical wear, and potential overshoot or rebound after stopping are additional considerations. The required stopping characteristics depend on risk assessment, standards, and specific application.

Factors influencing stoppesegenskap include actuator or brake torque, inertia of moving parts, friction and wear, control logic, power supply, and environmental conditions. Design approaches to improve stoppesegenskap include selecting appropriate actuation (electromechanical, hydraulic, pneumatic), implementing redundant safety circuits, optimizing control algorithms for fast and robust response, and ensuring regular maintenance and testing.

In practice, definitions and requirements vary by field: emergency stop devices in machinery, railway braking systems, and process safety interlocks all address stoppesegenskap, but with field-specific definitions and tolerances. See also emergency stop, braking system, and safety interlocks.
