The possibilities and limits for the subsequent processing and analysis are already determined when recording noises and vibrations.

Three time blocks are planned for this topic. We will highlight the areas relevant for data acquisition, starting with the sound field, the selection and conditioning of suitable sensors and front-ends, the efficient use of the recording software and the documentation of the results.

Program:

Block Acquisition:

• Sound field, characteristics of sound signals
• Time signals and their properties
• Parameters for data acquisition and A/D conversion
• Limits of signal recording
• Standard sensors: microphones, accelerometers
• Special sensors: binaural sensors, digital sensors (CAN, OBD, FlexRay)

Block Recorder 1:

• Using the Sensor Library, procedure for creating a sensor list
• Setting up a channel list, adjusting the sampling rate and other parameters according to the sensor used
• Trigger

Block Recorder 2:

• Online monitoring
• The "Flow Control" sequence control
• Documentation of measurements

Here you get the ideal introduction to the versatile and flexible analysis software ArtemiS SUITE. You will get to know the philosophy, the program structure and the most important functions. The practical presentation will prepare you optimally for using this powerful tool.

Practical examples will give you a clear illustration of the targeted use of basic features.

Program:

Block Basic 1:

• Concept of the ArtemiS SUITE
• Customize the program interface
• Creating a Pool Project
• Use of the Mark-Analyzer for the presentation of results
• Playback and zoom functions

Block Basic 2:

• Settings for the diagram:
  • Configuration of the title and legend
  • Assigning line colors
  • Arrange several diagrams in a meaningful way
  • Presentation of the Data-Viewer for the representation of several measurements in one diagram
• Export of diagrams to PowerPoint®.
• Cutting of recordings, creation of marks

Bock Analysis 1:

• The basic analyses
  • Level over time, significance and use of weighting functions
  • Frequency analysis with the Fast Fourier Transformation (FFT): function and meaning of the different parameters, averaged FFT and FFT over time (3D diagram, Campbell plot)

Block Analysis 2:

• Continuation of basic analyses:
  • third-octave/n-th octave analyses
• Use of speed information in the basic analyses: level and FFT vs. RPM
• Basics of order analysis

Block Playback:

• Configuration of the player
• Online filtering: The different filter types, grouping filters, assigning filters to a Mark Analyzer

Block Statistics:

• Use of statistical functions in the statistics pool
• Differences between mark and channel statistics
• Creating tolerance schemes

This training provides you with a deeper insight into the evaluation of speed signals and special analysis methods in ArtemiS suite. Learn how to optimally handle analyses of various reference variables such as speed or velocity so that you can use these effective tools in a targeted manner.

Among other things, various methods for the analysis of engine orders are presented. Here the focus is on the question which methods are suitable for special problems. In this context, we will also show you how you can use order filters to lower or raise the level of individual orders during playback in order to achieve your target sound.

Program:

Block RPM 1:

• The Decoder Project, decoding OBD, CAN and FlexRay data
• What is a control channel?
• Use of other reference variables in analyses, e.g. level vs. vehicle speed

Block RPM 2:

• Dealing with pulse channels
• Definition of pulse sensors in the recorder
• Decoding of pulse channels in the decoder project, e.g. for torsional vibration analysis

Block Order Analysis 1:

• Definition of the term order
• Limits for CAN/OBD/FlexRay based RPM measurement
• Basic settings of the order analysis                          

Block Order Analysis 2:

• The different calculation methods, when to take which?
• Order cuts
• Time Weighting

Accurate documentation of measurement data is essential for efficient work. ArtemiS suite offers an easy to use concept to document data directly during data acquisition or at a later time.

Creating reports often takes a lot of time, especially if the reports are to be brought into a defined format. ArtemiS suite offers a powerful reporting module that can generate standardized reports with just a few mouse clicks. You can refer to the documentation of the measurement, if everything is optimally configured, the report can even be generated automatically directly after the measurement without any further steps, this training shows you how.

Program:

Block Documentation:

• Creation of documentation templates
• Use of external data sources to simplify the documentation, e.g. an Excel table with gear-motor combinations as a basis for the selection options in the documentation
• Creating and using a database for measurement results

Block Reporting:

• Concept of reporting in ArtemiS SUITE
• Creation of report templates
• Creation of automated reports directly after the measurement

In this training, you will learn how to use the new automation function of ArtemiS SUITE to automatically handle frequently recurring tasks. You will learn how to combine an individual sequence of work steps in an automation project that repeatedly processes individual files or large amounts of data in a linear fashion at the push of a button.

Program:

Block Automation 1:            

• Concept of an automation project
• Differences to the Pool Project
• Automated channel selection by unit or name
• Automated cutting of marks based on speed information or at defined times
• Use of different analyses for different units

Block Automation 2:

• Use of variables for speed, channel names etc.
• Bundling of sequences
• Selection of measurement data based on file names or documentation

Block Automation & Reporting:

• Use of automation projects for automated report generation
• Differences to reports generated from pool projects
