WitrynaIn modal analysis, a model of the dynamic properties of a structure is created. The model is described by a set of modal parameters from which the structural behaviour can be predicted in different situations. Modal analysis is used in a wide variety of applications from securing structural integrity to improving comfort. An ideal impact to a structure is a perfect impulse, which has an infinitely small duration, causing a constant amplitude in the frequency domain; this would result in all modes of vibration being excited with equal energy. The impact hammer test is designed to replicate this; however, in reality a hammer strike … Zobacz więcej Modal testing is the form of vibration testing of an object whereby the natural (modal) frequencies, modal masses, modal damping ratios and mode shapes of the object under test are determined. A modal test … Zobacz więcej A shaker is a device that excites the object or structure according to its amplified input signal. Several input signals are available for modal testing, but the sine sweep and random frequency vibration profiles are by far the most commonly used signals. Small objects … Zobacz więcej • Modal Analysis • Vibration • Cushioning • Shock absorber • Shock (mechanics) • Shock response spectrum Zobacz więcej
