1. Import/Export of measurement data

The following instructions describe the import/export of

measurement data in MDF and CSV format into/from jBEAM

Lab/Durability/Powertrain (Starter/Professional/Ultimate).

Import of MDF data

1. Select menu File → Import Values → MDF (ASAM v3/v4).

2. Select the MDF file to be imported in tab File Chooser.

3. Select the load status for each channel included in the

MDF file in tab Channel Selection:

The load status can be changed by clicking on the icons:

Channel shows up in jBEAM project and values are

imported

Channel shows up in jBEAM project but values

aren’t imported (will be imported automatically

when channel is used within project)

Channel does not show up in jBEAM project and

values aren’t imported

4. Import the data by clicking the Open button.

Import of CSV data

1. Select menu File → Import Values → ASCII.

2. Select the CSV file to be imported in tab File Chooser.

3. Select tab File Structure to define the structure of your

CSV file to be imported.

a. Meta data: Select the checkbox Load meta data and

define the first and last line of the meta data section if

meta data shall be imported.

b. Data start: Define the start line of the data section.

c. Separation character: Define the channel separation

character.

4. Select tab Meta Data and define the separation character

for the meta data:

5. Select tab Channel Header to define name and units of

channels. The header information can be entered for all chan-

nels or channel by channel and manually or from the file by

selecting the appropriate line.

a. Name: Define the channel name either by entering a name

manually or selecting the appropriate line in the file.

b. Unit: Define the unit either by entering a unit manually

or selecting the appropriate line in the file.

c. Time information: If the file does include an explicit

time channel this step (5c) can be skipped to proceed

with step 6. If not, define:

•x0: Start time (e.g. 0.0)

•Δx: Time increment per sample (e.g. 1.0E-4)

•x-Unit: Unit of time (e.g. s)

6. Select tab Data Formats to define the decimal separator

and time channel:

a. Decimal separator: Define the decimal separator

b. Time channel: Define the explicit time channel if the

file does include one by selecting checkbox Manual

X-channel and the appropriate channel (if not see step 5c)

7. Import the data by clicking the Open button.

Export in CSV format

1. Select menu File → Export Values → ASCII

2. Select tab Channel data:

a. Channel selection: Select the channels to be exported.

By default, the checkbox export all data is selected. If

you like to export specific channels only unselect the

checkbox export all data and select the channels to be

exported in the list Available Channels. By pressing the

button “>” you can add the selected channels to your

Selected Channels list. Only channels in the Selected

Channels list will be exported.

b. Separation character: Select the separation character for

the CSV export format.

c. Export channel properties: By default, channel

properties (name, unit, etc.) are exported. If the infor-

mation is not needed in the data export unselect the

checkbox Export channel properties.

d. Export values: By default, channel values of select-

ed channels are exported. If channel values are not

needed for instance if only channel properties are to

be exported unselect the checkbox Export values.

3. Select tab File Chooser and define the directory and file

name for the data export

4. Export the data by clicking the Export button

2. Visualization of data

The following instructions describe the visualization of mea-

surement data and analysis results and the zooming within

graphs.

Visualization of data in y/t graphs

Data and analysis results can be visualized in the working sheet

section (D) by simply drag & drop the data from the explorer

ing Ctrl key while selecting the desired data in the explorer.

Common and multiple y-axis

If multiple signals are visualized in the same graph the y-axis

is common by default.

If multiple y-axis (one per signal) are preferred the graph

settings need to be configured as follows:

Right click on graph → Modify… → Button Stacked A

The y-axis can be reset to a common axis by selecting

Stacked B.

Zooming within graphs

• Window zoom: «Ctrl + Alt + Left Mouse Button»

• Axis zoom: «Ctrl + Left Mouse Button» on axis

• Moving signal within graph: «Ctrl + Left Mouse Button»

Cursors

Cursors can be added to a graph by Right click on graph →

Modify… Cursor.

The Analysis and Delta Cursorset are available and can be

selected by clicking on the corresponding button:

• Analysis cursorset:

The analysis cursor set consist of one y/t cursor pair

which indicates the y and t values of one single point of

a measurement curve.

• Delta cursorset:

The delta cursor set consists of two y/t cursor pairs

indicating the y and t values of one single point of a

measurement curve each. In addition y and t delta values

are indicated.

3. Analysis of data (Statistics and FFT)

The following instructions describe the analysis of mea-

surement data, specifically statistics and FFT. This is not

an exhaustive description of the analysis functions of

jBEAM, but is intended to show the concept of how

analyses are performed in jBEAM.

Statistics

Following example describes the calculation of min. and max.

value of an acceleration signal.

1. Select menu Math → Statistic → Extract Statistical Values

2. Window for statistical values calculation shows up

a. Enter a name for the statistics calculation:

b. Select the data importer and channel for the statistic

calculation (in this example the acceleration signal):

c. Select statistical quantity

to be calculated

(example: the minimum):

d. Use the proposed name for

the result or enter a name

(unselect checkbox to do so):

→Repeat steps b to d to add calculations for other

statistic values (maximum value in this example)

e. Confirm the calculation by clicking the OK button

3. The calculated statistic values are listed in the Explorer

window under the given names:

4. By selecting the statistical values in the Explorer window

and drag & drop them onto the Working sheet the results

can be visualized

FFT

Following example describes the calculation of a FFT of an

acceleration signal.

1. Select menu Math → Vibration Analysis (FFT) → FFT-

Spectrum

2. Window for FFT calculation shows up

a. Enter a name for the FFT calculation:

b. Select your calculation - amplitude and/or phase spec-

trum:

c. Select the data importer and channel for the FFT

calculation (in this example the acceleration signal):

d. Select the windowing function to be used for the FFT

calculation:

e. Confirm the calculation by clicking the OK button

3. The calculated FFT is listed in the Explorer window under

the given name:

4. By selecting the FFT results in the Explorer window and

drag & drop them onto the Working sheet the results can

be visualized.
