Vibration Measurement/Data Handling
ZIN Technologies offers a wide variety of vibration measurement
data  handling/mining
and control assessment products both for space flight hardware/missions
and industrial clients.
Utilizing ZIN Technologies' multi-year experience in developing,
fabricating and operating NASA's microgravity acceleration
measurement hardware, we have developed a number of unique
data mining tools that can be utilized to extract acceleration
measurement time and frequency domain parameters. The following
is a brief summary of the standard data product tools available;
our data product tools are highly customizable for unique
requirements.
- Acceleration
versus Time-transient, quasi-steady, vibratory
- Interval Min/Max
Acceleration versus Time-vibratory, quasi-steady
- Interval Average
Acceleration versus Time-Vibratory, quasi-steady
- Interval RMS
Acceleration versus Time-Vibratory
- Power Spectral
Density (PSD) versus Frequency-vibratory
- Spectrogram
(PSD versus Frequency versus time)-vibratory
- Cumulative
RMS Acceleration versus Frequency-vibratory
- Frequency Band(s)
RMS Acceleration versus Time-vibratory
- RMS Acceleration
versus One-third octave bands-vibratory
- Principal Component
Spectral Analysis (PCSA)-vibratory
Real-time data/vibration
measurement analysis systems have been developed as well and
can be configured for maintenance/industrial control systems.
Vibration Control Analysis Products
A number of vibration control analysis and design products
have been developed for the prediction of disturbance levels
and design specifications. These analysis tools estimate disturbance
levels from disturbance sources on highly sensitive space
flight hardware to critical locations of science to critical
locations of science instrumentation or sensitive hardware.
These developed tools are available based on standard FEM
techniques that can be utilized to analyze and construct design
solutions for industrial and NVH problems. Active control
and standard passive vibration isolation techniques can be
specified and analyzed to develop system specifications for
dynamic systems design and fabrication.
