Duty cycle

1. User working point(s) analysis = Duty cycle

This allows computing the machine performance all over a considered duty cycle.

This duty cycle must be defined by using the next field: "Duty cycle description" and by clicking on the button "Set values".

Two ways are possible to fill in the table: either filling in the table line by line or by importing an excel file which all the working points of the duty cycle are defined.

Note: A working point is defined by a time, a speed, and a mechanical torque.
User working point analysis = Duty cycle
1 Select the “Duty cycle” option
2 Click in the button “Set values” of the field “Duty cycle” to open a dialog box to define the duty cycle.Refer to the next illustration which shows how to fill the Duty cycle table.
3 Button to validate the user input data
4 Button to run the computations
Note: Once the test results have been computed, new user working point and duty cycle values can be set, and results will appear instantaneously when relaunching the test.
User working point analysis = Duty cycle – Dialog box to define the duty cycle
1 Dialog box opened after having clicked on the button “Set values” in the field “Cycle description”
2 Browse the folder to select an Excel file which is described the duty cycle
3 Button to refresh the table data when the considered Excel file has been modified
4 Fields to be filled with data to describe the duty cycle to be considered
Note: The Excel template used to import a duty cycle is stored in the folder Resource/Template in the installation folder.An example of this template is displayed below.

2. User working point(s) analysis with thermal solving

When thermal solving has been selected in the settings, it is mandatory to define the driving cycle with a list of working points.

This duty cycle must be defined by using the field: "Duty cycle description" and by clicking on the button "Set values".

Two ways are possible to fill in the table: either filling in the table line by line or by importing an Excel file which all the working points of the duty cycle are defined. The Excel sheet format will be the same than in the previous section.

Note: A working point is defined by a time, a speed, and a mechanical torque. The time must always begin by 0 second.
User working point analysis = Duty cycle
1 The “Duty cycle” option is mandatory when thermal solving is selectedClick in the button “Set values” of the field “Duty cycle” to open a dialog box to define the duty cycle.Refer to the next illustration which shows how to fill the Duty cycle table.
2 The index plot allows us to select a working point of the cycle for displaying data and maps which are corresponding to its thermal properties.
3 Maximum time step which is considered to discretize the driving cycle sequences.

There will be no time step greater than the value written in that field (10 s in our example).The minimum value = 0.01s, the maximum value = 3600s.The default value = 10s
