REDUCTION OF STRUCTURE-BORNE NOISE THROUGH THE COMBINED APPLICATION OF MODAL AND SIGNATURE ANALYSIS TECHNIQUES.

An investigation to determine an effective and practically acceptable method of reducing vibration and noise radiation from a wingbase of a type which is commonly used in the construction of transfer machines is described. The wingbases were shown to be significant radiators of structure borne noise which was generated by the supported machining head. Combined application of modal and signature analysis techniques also permitted an effective …
