kilengése

Kilengése is a Hungarian term that describes the deflection, swing, tilt, or deviation of a body or component from its reference position or orientation. It is used in fields such as physics, engineering, and geology to denote displacement resulting from forces, moments, or dynamic motion. Kilengése can be translational (linear displacement) or angular (change in orientation).

Causes of kilengése include mechanical loads, thermal expansion, gravitational effects, centrifugal or Coriolis forces in rotating parts, misalignment, wear, and material deformation. In structures it appears as bending or lateral displacement; in machines it can show as shaft deflection or angular tilt under operation.

Measurement and calculation: kilengése is typically expressed as a linear deflection δ (meters or millimeters) or an angular deflection θ (radians). It is often evaluated against design tolerances. For example, a cantilever beam with an end load has deflection δ = F L^3 / (3 E I). In rotating machinery, kilengése can lead to vibration if unbalanced or misaligned, affecting performance and longevity.

Applications: in structural engineering, limits on kilengése ensure serviceability of beams, bridges, and frames. In mechanical design, controlling shaft and bearing kilengése prevents contact, noise, and wear. Monitoring methods include dial gauges, laser displacement sensors, strain gauges, and vibration analysis.
