Appendix A

Bump test (impact test)

To analyze the resonance of the system structure and element member of machine,

we have to know the natural frequency of that past, it is not easy to calculate the natural

frequency of the complicate structure. Bump test is commonly used to determine the

natural frequency.

We use impact hammer to hit the structure of which we want to know natural

frequency and set up the window function of measurement to be uniform or rectangular

window.

For this research, install the accelerometer at the point PC1,PC2 (bearing housing),

PC3 (head cover) and PD1 (draft tube), Hit the bearing housing at the opposite side of the

accelerometer and measure the vibration in mm/s, same as when we measure the value of

vibration. Do the same at all point.

The result of vibration measurement as shown in figure A1 is for bump test of unit

#5. Each peak amplitude in 2000 Hz of spectrum is natural frequency, about 150.96 Hz,

254.7 Hz, 467.17 Hz, 697.19 Hz and 889.06 Hz frequency at each point of measurement.

Most of the natural frequency that shown in bump test has high amplitude cause by

resonance affect and shown spectrum
