#+TITLE:Measurement of the sample vibrations when rotating the Spindle

Measurement:

  • one geophone on the marble
  • one geophone at the sample position

Every stage is powered on.

Data file Description
data_001.mat nothing is turning
data_002.mat spindle is turning at 1rpm

Mesures Dynamiques Rotation Slip-Ring

All the stages are OFF

One geophone on the marble (Col 1) One geophone at the sample location (Col 2)

Voltage amplifier setup: 60dB AC 1kHz

LPF added at the input of the voltage amplifiers

Goal:

  • Identifify the vibration induced by the rotation of the Slip-Ring and Spindle
  • meas24: All OFF
  • meas25: 6RPM: only the slip-ring is ON and rotating (spindle OFF)
  • meas26: 6RPMZ; Slip-ring and Spindle ON
