Sine Reduction Test - Sine Processing With COLA Signal

Integrate and synchronize the data acquisition system seamlessly with your vibration shaker COLA signal and perform a powerful evaluation of structural properties on unlimited channels in real-time. Dewesoft sine processing solution is easy to set up and will get you measuring right away.

Real-time Sine Processing Analysis Introduction

Sine reduction (also known as sine processing) is a method of performing structural tests on large structures. The method can identify and analyze natural frequencies by exciting them with  a sweep of single frequencies.

Vibration signals from accelerometers and force sensors mounted on the structure are measured together with sweep frequency and are being tracked, recorded and analyzed by the data acquisition system in real-time. As desired output, sine processing returns the structural resonance frequencies, amplitudes, phase, THD (total harmonic distortion) of response and also transfer functions between excitation and response points.

​The COLA signal from the vibration shaker controller is used as the frequency reference for the signal analysis.

What is COLA signal?

The COLA signal (Constant Output Level Amplitude) is a constant voltage sine wave which frequency tracks the Drive signal frequency during the Sine Control test. It is the same frequency as the excitation frequency.

Dewesoft sine processing solution is the most powerful structural analysis tool which supports the evaluation of responses and transfer functions on an unlimited number of channels, all in real-time.
Picture

Sine Processing Functionality

Sine vibration testing applies a single frequency to a test item and selectively excites resonant structures within the device. In a swept sine test a vibration sine tone is ramped up and down through a range of frequencies and for a specified rate and duration.

Dewesoft system provides the real-time calculation and functions of the excitation frequency:

Detection of amplitude, frequency and phase of the vibration reference
Extraction of harmonic components (Peak and RMS) of all measured signals
Extraction of the overall broadband signal (Peak and RMS) level of all measured signals
Calculation of transfer function (FRF, coherence, etc.) and the total harmonic distortion (THD) between the reference signal and any point measured on DUT
Calculation of the fundamental and its harmonics​

The Best Signal Amplifiers with 160 dB Dynamic Range

SIRIUS data acquisition systems offer the world's best signal amplifiers for vibration sensors (IEPE, MEMS, Charge).

Dual Core ADC Technology - Dual 24-bit AD Converters
​
Amplifiers offer a high dynamic range up to 160 dB and signal to noise ratio of more than 130 dB. This is 20 times better than 24-bit systems and 20 times less noise.

​The Dual Core ADC technology solves often faced problems with signal measurement - input overload, noise and artificial frequencies in the signal caused by aliasing. The input signal can be higher than expected (out-of-range) and therefore clipped by the ADC. This will result in an incorrect measurement and you will have to repeat the test all over again.

Dual Core ADC technology prevents these problems. Each channel amplifier has two AD converters that always measure the high and low gain of the input signal. This results in the full possible measuring range of the sensor and prevents the signal from being clipped.

Galvanic Isolation

The data acquisition system includes high galvanic channel-to-channel and channel-to-ground isolation (+/- 1000 V). It even includes an isolated sensor excitation.

With such isolation, we have no problem measuring high voltage potentials and no problem with common-mode voltages. We are also safe with measurements like vibrations, temperatures or any other measurement where non-isolated sensors are placed next to the high voltage potential against the DAQ system ground. In such cases, a non-isolated DAQ system would burn or at least give faulty wrong results. With SIRIUS it is just one thing less to worry about.

Digital isolation has another big advantage-preserving the frequency bandwidth of the amplifiers. SIRIUS provides "worry-free" measurements, less noise, no ground loops, and the best possible signal quality.
Picture

TEDS Sensor Technology

Dewesoft data acquisition systems support TEDS sensor technology for automatic sensor detection and setup. Simply connect the sensor to an input channel on our data acquisition system and the sensor will be automatically detected and set up immediately.

Both reading and writing to TEDS (IEEE 1451) are supported directly in the Dewesoft software. An extensive sensor database and editor are available which gives you a simple way to build your sensor database for future use.

Dewesoft data acquisition systems are compatible with any 3rd party vibration sensors including IEPE, charge and MEMS accelerometers. In other words, you can always use your existing sensor inventory.

From Test to the Printed Results

Not only our sine processing solution offers advanced analysis features but it also offers extensive data reporting functionalities.

PDF Report Generation

Dewesoft software includes extensive PDF data reporting and printing capabilities. When data is analyzed you can generate PDF reports of your data and visual displays with a single click. Advanced reports are possible with the creation of custom templates.

Video or Image Export

The visual screens of the tests can be exported into images or video files for use in PowerPoint or other presentations.

Data Export

Dewesoft software always stores measured raw data for later analysis and can also be exported into various standard data formats. Formats like UNV, Excel, Matlab, Flexpro, Diadem, Wav and many others are supported out of the box.
