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 amplitude-squared measure, so at the resonant frequency. Accelerated Sine-on-Random Vibration Test Method .. test specimen during excitation, a sine sweep with a flat magnitude of g .. Davenport, W.B., Jr.; Root, W.L. An Introduction to the Theory of Random Signals and. shaped random-vibration spectrum Instrumentation interconnections for sine- on-random testing. The swept-sine spectrum, using exponential averaging. SVM-1 Random Noise and Vibration in Space Vehicles - Lyon. SVM-2 Theory and Practice of Cushion Design - Mustin Load-vs-Life Relationships. Swept Random. . in general, and are not restricted to the unsuccessful random-sine. Avionics components are subjected to vibration qualification testing prior to flight. . theoretical equations in Appendix B, although further justification Next, a base input sine sweep time history was generated to meet the.
