Mr Wald, Thanks for your input. In addition to that, i currently used manually fabricated brackets ( 'L' shape bracket ) for proximity probe installation, however it give less accurate result. And then i'm thinking about magnet mounting instead of using those brackets.Installation also will be...

Hi, Any recommended magnet mounting for non-contact proximity probe?it's intended to be used as temporary installation at hydro turbine-generator

Sir Greg, To obtain mode shape of a structure, a minimum set of FRF measurements must be taken either a single fixed input and many outputs or between a single fixed output and many inputs.Why not using many inputs and many outputs?

Dear Mr Greg Locock, Could you please go in detail about the mode shapes & how to identify from FRF spectrum? Thanks

End winding was divided into 17 quadrants where the measurement points were at its inner and cap.

Yes, i'm using triaxial probe for measurement. All data is in all 3 directions. Any advice?

Actually, i'm trying to predict the system response & structural dynamic behavior by modal analysis. All measurements(FRF & its phase) already been taken using CSI 2310 with good quality control of the coherence.In addition, i also have no idea what is the mode shape & how to identify it?

Dear sir, First of all, thanks for your response. Actually, i'm intended to develop experimental modal analysis of generator's end windings (Both DE & NDE sides).Bump tests already been done & the result shows that there are natural frequencies appeared on 95 - 115 Hz (area of interest: 2x of...

Could anyone explain to me, what is the crucial steps in developing modal analysis?
