stabilisators

Stabilisators, also spelled stabilizers in American English, is a broad term for devices, systems, or substances that reduce unwanted motion, maintain orientation, or prevent degradation. They can be passive or active, mechanical, electrical, or chemical, and they appear in many fields to enhance safety, performance, and longevity.

In mechanical engineering and transportation, stabilizers are used to limit movement and keep structures steady. In automobiles, anti-roll bars connect opposite wheels to reduce body roll during cornering. In ships, fin stabilizers or Gyroscopic stabilizers lessen rolling in rough seas. In aircraft, horizontal and vertical stabilizers (tail surfaces) provide pitch and yaw stability, often complemented by active flight control systems.

In electrical engineering, stabilizers refer to devices that maintain a consistent voltage or current. Voltage stabilizers or regulators ensure appliances receive steady power, and stabilizing circuits are integral to power supplies, data centers, and grid protection. Autopilots and control systems in aviation and maritime contexts also function as stabilizing mechanisms.

In materials science and chemistry, stabilizers are additives that prevent degradation or alter a material’s behavior. Antioxidants, UV stabilizers, and thermal stabilizers are common in plastics and polymers to extend life under heat and light. Stabilizers also serve in foods and cosmetics to maintain texture, suspension, or emulsions, such as thickeners and emulsifying agents.

In biology and medicine, stabilizers can refer to muscles and soft-tissue structures that stabilize joints during movement, helping to maintain posture and control. Examples include the rotator cuff and other synergistic muscle groups that support joints without producing primary motion.
