Abstract
The method and apparatus of the invention simultaneously induces the same variable frequency mechanical vibrations in a test part and a standard. The vibrations of the two are converted to signals which are either displayed for comparison purposes or automatically analyzed for differences. Advantageously, the signals are electrical signals providing spectra which are analyzed for differences in amplitudes produced by the signals. Where the parts are separately supported, they are held with substantially the same force and are maintained against the vibration inducing mechanism with the same force. Where accelerometers are used, they are held with substantially the same force against the vibrating parts.
