摘要

Traditionally, when test engineers have performed sine resonance track and dwell tests, they have controlled the frequency of the resonance with little concern for the phase of the resonance. There is good reason for this. Since resonance occurs when a material's vibrations are reinforced (constructive interference) by the 'reflected' waves in the material, it can be assumed that the ideal phase value for a resonance is 90°. Therefore, controllers would often set the default phase setting for a resonance to 90°.
