Vibration resistance
Vibration resistance refers to the durability of a technical device or other product in the event of vibration or extremely high short-term acceleration or deceleration, for example in the form of a shock.
Vibration resistance and shock resistance
Shock resistance covers both a single shock and vibration as a shock. However, sometimes the shock is referred to separately as "shock resistance". So for shock resistance in the sense of a shock or under the term shock resistance the unit of measurement g force per time z. B. 20 g / 20ms can be specified. When specifying the shock resistance in relation to vibration, in addition to the g force and time, the frequency, e.g. B. in Hz. For example, a residual current circuit breaker has a vibration resistance value of> 5 g (f ≤ 80 Hz, duration> 30 min.).
use
Vibration resistance is used, among other things, as a quality property of hard drives or car radios . Many measuring instruments have a shock resistance rating.
