Frequency response function
measurement

CF-3600AT、CF-3600AR
CF-3800AT、CF-3800AR
Resonance may cause the chatter vibration of robot or machine
tool, or noise/vibration of vehicle and home appliance. For the
analysis of resonance, the most popular method is frequency
response function measurement of the object by using impulse
hammer. As neither attaching excitation tool to the structure
nor long measurement time is required, excitation by the impulse
hammer is the most ideal method for on site measurement
including trouble shooting. Maximum of 8-ch* simultaneous signal
processing, at 40kHz range and 6400-point frequency analysis can
be performed.
* When CF-3800A or CF-3600A has an
optional CF-0364 4-ch optional expansion unit. |

Tracking analysis
|
|
CF-3600AT、CF-3800AT
Rotating machinery such as engine or compressor must cover wide
range of rotation speed from very low to high speed. For those
rotation machineries, resonance which is generated by rotation
speed and natural frequency of the each component (parts such as
rotation shaft, gear, blacket etc.) will be the most significant
problem. In case of tortional vibration in large power
generators and the like, resonance creats great vibration
excitation energy that exceeds the tolerance of the machinery
and can cause serious accident to be destroyed. When the
rotating machinery makes vibration at a certain rotation speed,
the rotation tracking analysis is one of the effective method to
identify the rotation speeds at which rotating parts generate
the noise/vibration, and how many times of the frequency
component (order) of noise/vibration are generated. |

and diverse analyses such as multi-frequency range analysis,
signal processing by digital filter with PC analysis software.

Real-time octave analysis
|
|
CF-3600AR、CF-3800AR
In order to solve the noise problem, the frequency analysis is
required. Octave analysis has long been used as noise analysis.
An octave represents that frequency with ratio of 1:2 to the
frequency that is, double the frequency. The human ear senses
sound in geometric progressions to the frequency. In view of
this feature, a series of octave bands based on 1kHz frequency
has been standardized. The sound pressure of each band is
obtained through the standardized band-pass filter. The octave
band based on 1 kHz frequency is called the 1/1 octave band,
while the bands formed by dividing into third are called 1/3
octave bands. Real-time octave analysis software can perform
simultaneous frequency analysis with maximum of 8-ch*.
* When CF-3800A or CF-3600A has an
optional CF-0364 4-ch optional expansion unit. |

|
1/N Real-time octave analysis
|
|
Option:DS-0224
By adding optional software of
DS-0224 1/N real-time octave analysis function to
CF-3600AR/CF-3800AR, the signal power of noise/vibration can be
analyzed and displayed as 1/6, 1/12, 1/24 real-time octave band.
Simultaneous analysis from 0.701Hz to 17.20kHz (1/24 octave) can
be performed. Also DS-0224 can simultaneously measure the
following four values; maximum value, minimum value, power
average value and power sum value.

Ch1, ch2, ch5 and ch6 (CF-3800A) |
* DS-0223 1/1 and 1/3 real-time
octave analysis software is required in the use of DS-0224.
|
 |
| |
|
Octave tracking analysis
|
|
Option:DS-0243
Adding optional software of DS-0243 octave tracking analysis
function enables CF-3600AR/CF-3800AR to perform octave tracking
analysis. This software can analyze and display the level trend
of each band for each rotation speed after input of rotation
data and retrieving an each fixed rotation as real-time octave
analysis data.
* 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
The 1st order vibration will become large by the unbalanced
phenomenon of rotation. When the rotation speed is changed with
unbalance, the resonance may be generated and it is so
dangerous. The unbalance must be corrected. However, the
conventional vector calculation method of drawing a vector graph
and performing vector calculations takes a long time, making it
difficult to carry out on site field balancing. DS-0227 filed
balancing software can calculate easily single plane for one
condition, single plane for two conditions, and two planes for
two parameters of field balancing. |
