Preface
This manual describes the Bump Test and how to apply it using the Dynamix
2500 data collector. You install the extension module with the Bump Test Secure
Digital (SD) card.
Installing Optional Extension Modules on page 7
for installation
instructions.
When using the Dynamix 2500 data collector and the Bump Test extension
module, you can do the following:
•
Determine natural (or resonant) frequencies of a machine or structure.
•
Identify a structure’s resonant modes.
•
Change the resonance frequency to reduce or eliminate damaging
vibration levels.
Optional Extension
Modules
These are the optional extension modules for the Dynamix 2500 data collector:
•
1441-DYN25-4C, 4-channel Activation
(1)
The 4-channel activation lets you take 3 and 4 channel magnitude, time
waveform, spectra, and Offroute measurements.
•
1441-DYN25-MBMP Bump Test
The bump test (or hammer test) determines the natural frequencies of a
machine or a structure.
•
1441-DYN25-MBAL Balancing
The balancing test resolves single-plane, two-plane, and static-couple
balances with high precision.
•
1441-DYN25-MFRF Frequency Response Function
The FRF test lets you determine the natural frequencies of a machine as
well as sophisticated information about the frequency response of the
structure being tested.
•
1441-DYN25-MREC Time Recorder
The Time Recorder test uses a the instrument as a data recorder for real-
time data acquisition and analysis.
•
1441-DYN25-MRUC Run Up Coast Down
The RUCD test records and analyzes data from intermittent events and
transient vibration signals from non-steady state machines.
