Integrate the machine mechanical properties and kinematics (number of cylinders, machine cycles, timing diagram) into NVGate, the Noise and Vibration software platform. The Advisor offers an easy software confi guration and results displays based on the machine characteristics and instrumentation
Advisor helps to the software configuration depending on the engine model
Various engine models exist. They are different in different points:
The timing information corresponds to the machine kinematics.
One important constraint when dealing with vibration measurement for machinery health monitoring is the measurement reproducibility. Indeed to be able to compare measurements acquired at different times, it’s necessary to use exactly the same instrumentation: same transducers, same position on the machine.
To help the user on this point, EngineDiag proposes to define a typical instrumentation for each type of machine.
The advisor gives a status about the software configuration depending on the engine model.
Using different colors, the advisor indicates the status of the NVGate configuration.
In addition to give the status of the configuration, the advisor proposes the solutions to set up correctly the software.
The specificity of the results proposed by EngineDiag is to integrate the machine kinematics. In each window the cycle overviews are displayed showing the different phases.
Based on the Synchronous order analysis, this result shows the time information of the different cylinders with the cycle overview.
The overall level calculated in EngineDiag is the overall level of the machine cycle averaged on the measurement. To go further and identify the fault more in details, overall level of the different kinematic phases (intake, compression,…) can be extracted.
The method implemented in the software is based on the Wigner-Ville algorithm.
The advantage of this display is to provide all the results in one window and intuitive tools for the analysis.
