CF-3850T, CF-3850R
Resonance may cause not only chattering vibration in robots and
machine tools but also vibration and noise in automobiles and
home appliances. The most popular method for analyzing resonance
is measurement of the frequency response function of the object,
using an impulse hammer. Excitation by an impulse hammer is the
ideal choice of the on-site measurement for trouble shooting
because it reduces measurement time without the need to mount
the object on an exciter. It enables simultaneous processing of
up to 8ch*, 40 kHz range and 6,400 points of frequency analysis.

Tracking analysis
|
|
CF-3650T, CF-3850T
Rotating machinery such as engines, compressors and turbines
etc. must cover wide range of rotating speed from very low to
high speed. The most important issue is resonance caused by the
rotating speed of the machinery, in which the rotation frequency
is the same as the natural frequency of the rotating machinery’s
components (e.g. axles, gears and brackets.). In case of torsion
vibration in large power generators and the like, resonance can
cause serious accidents, creating vibration excitation energy
that exceeds the tolerance of the machinery, destroying it.
Rotation tracking analysis is the effective method to identify
the rotating speed at which resonance occurs in rotating
equipment, and which components and orders (multipliers) of the
rotating speed generate noise or vibration. |

The ability to directly store the
original signal waveform to the HDD of CF eliminates the needs
to save to a data collector then retrieve it. This also allows
you to store the data in non-degrading digital status. Use the
data recorded via the throughput disk function to analyze it on
the CF as well as the offline analysis at the PC on which DS or
DS installed. By changing the measurement and analysis
conditions allows for flexible analysis.

Real-time octave analysis
|
|
CF-3650R, CF-3850R
In order to solve the noise problem, the frequency analysis is
required. And octave analysis has long been used for frequency
analysis. An octave is a frequency with ratio of 1:2 to the
frequency that is, double the frequency. The human ear senses
sounds in geometric progressions to the frequency. A series of
octave bands based on 1 kHz has been standardized, and the
acoustic pressure level of each band. The octave band based on 1
kHz is called the 1/1 octave band, while the bands formed by
dividing into third are called the 1/3 octave bands. CF performs
real time octave analysis for 4 channels simultaneously.

DS-0224: Option
This software can analyze and
display the signal power of noise and vibration as 1/6, 1/12,
1/24 real-time octave band. Simultaneous analysis up to 2ch from
0.701 Hz to 17.20 kHz (1/24 octave) can be performed. Also the
DS-0224A can measure the following four values simultaneously;
maximum value, minimum value, power average value and power sum
value.

DS-0224A. |
 |
| |
|
Octave tracking analysis (option)
|
|
DS-0243: Option
This octave tracking analysis software can analyze level trend
of every band for the rotating speed by input of rotation
information and retrieving of each fixed rotation as real time
octave analysis data. Note: DS-0223WA Real time 1/1 and 1/3
octave analysis software is required.
* DS-0223 1/1 and 1/3 real-time
octave analysis software is required in the use of DS-0243. |
 |
| |
|
Field balancing software (option)
|
|
DS-0227: Option
The trouble of rotation machinery is caused most frequently by
Imbalanced phenomenon of rotating shaft. So the balancing
correction is required, but the conventional vector calculation
method with drawing takes some time and it makes on-site field
balancing difficult. The DS-0227A measures the unbalancing
phenomenon easily and efficiently by calculating and displaying
the results of 1-plane 1-condition, 1-plane 2-condition and
2-plane 2-condition. |
