WebStep 1: Determine the duration of exposure time to vibrations under normal operating conditions. Only consider operating exposure and scrutinize work patterns for normal activity. For example, how many tools are operated daily and for what amount of time? Step 2: Determine the magnitude of vibration.
WebModal analysis is the study of the dynamic properties of systems in the frequency domain. Examples would include measuring the vibration of a car's body when it is attached to a shaker, or the noise pattern in a room when excited by a loudspeaker. smart dcc net worthWebFigure 3. With each test hammer hit - shown above in green - the vibration sensor (below, blue) registered a long ringing time since the massive metal structure has very low damping. The geometry model.
