Table 3

Change rates of natural frequencies under the effect of rotating speed or dead load.

/	1st mode	2nd mode	3rd mode	4th mode
With rotating speed, no dead load	1.17467	1.02615	1.00937	1.00508
No rotating speed, with dead load,	1.23577	1.05357	1.01532	1.00708
With rotating speed and dead load	1.37714	1.07864	1.02459	1.01216
