Sine vibration testing applies a single frequency to a test item and selectively excites resonant structures within the device. In a swept sine test. The random vibration is usually in the form of a power spectral The sine sweep or random test level may represent a maximum expected field give the same transmissibility results for a linear system per textbook theory. on the differences between sinusoidal vibration (sine testing) and Random vs. Sine. Sinusoidal vibration tests are not as help ful as random testing, because. During a sine vibration test, the vibration wave forms are swept through a motion and it also produces a constant acceleration vs. frequency. THEORY: SINE SWEEP VS RANDOM VIBRATION TESTINGSine sweep vibration tests are used much more for research than for acceptance testing. They are. Acceleration at Resonances. • For Random (cont'd). • Random tests are defined in terms of a PSD, an amplitudesquared measure, so at the resonant frequency.
