Mining Test - TKPH

The TKPH plugin for VBOX Test Suite gives you the ability to generate reports to summarise the performance across different circuits and check if the vehicle TKPH is exceeding the tyre TKPH.

The plugin includes features such as algorithms for cycle TKPH, average TKPH, Michelin/Bridgestone TKPH corrections and inputs for Load/Dump locations, ambient temperature, vehicle wight data and tyre specification data.   

When you add a new test, the test settings window will automatically open when the test opens. 

1. Enter the time that will be used to calculate the moving average. 
2. Enter the shift start times.
3. Enter the default ambient temperatures for the two shifts.
4. Decide if you want to display Michelin corrections in the report.
5. Decide if you want to display cycle TKPH in the report. 
6. Decide if you want Test Suite to generate a table of cycles and add it to the last page of the report.
7. Enter the minimum load and dump times.
8.  Enter the maximum load and dump speed. 
9. Enter the duration of the interval where TKPH is calculated. 
10. Decide if you want the cycle calculations generated as a .csv file.
11. Click OK.

1. Click on the Edit Data button in the Session section of the Test Setup tab, or on the session tab in the Results area, to open the Session Data window and enter or import the relevant data for the session. 
2. Enter the Vehicle information for the report header. 
3. Enter the Weight information. 
   
   This allows the plugin to calculate TKPH based on the weight values for the specific vehicle in the test. 
   You can import the the weight information by clicking on the Import button and navigating to the relevant .vbses file. You can find a database with files for common mining vehicles here. 
   
   Enter the weight values as specified in the manufacturer's vehicle specification. 
    
4. Enter the Ambient Temperature information.
5. Enter Tyre Data.
   
   This allows Test Suite to apply tyre manufacturer TKPH corrections and display relevant information in the report.

   Add Tyre

   To compare site TKPH of the vehicle against selected tyre specification, ensure that the following is entered as a minimum:
   
   Tyre Size – Enter tyre size as per the standard tyre size naming convention (i.e. 46/90R57, 40.00R57, 40.00-57). Below you will see the respective section width, aspect ratio, tyre construction type and rim size being detected based upon the tyre size convention.
   
   Manufacturer – For tyre manufacturers that apply corrections (i.e. Bridgestone, Michelin, Yokohama), ensure that the manufacturer is chosen from the dropdown so the plugin can identify the tyre brand and apply corrections accordingly.
   
   TKPH, Tread Pattern, Compound / Spec – Enter this information as listed in the tyre manufacturer data books. TKPH must be a numeric value. According to 'Options', TKPH will be entered if km/h is set and TMPH will be entered if mph is set.

6. Click OK to confirm and close the session data. 

The results from each run in your test will be populated in the Results table. 

You can add and remove columns to the results table.

You can add columns to the Test Results area by clicking the Add button on the Test Setup ribbon or right-clicking anywhere in the Test Results area and selecting the Add option. This will display a drop-down list of all the available channels to display in a results column. By default, this value is displayed as an At End value, which will display the value of the parameter at the end of the run.

You can remove a column by clicking the X that appears when you hover over the column title. If you have removed a column, you can add it again by clicking the Add button and selecting the desired channel.

By default, a column is added without a condition. You can change this by clicking on the column header for the channel you wish to add a condition for. The selected column will be highlighted in yellow. Click on the condition dropdown in the Data column area on the Test Setup tab and select the required condition.
 

You can choose the following conditions for the main results:

• Avg
  The mean average of the parameter during the run.
• Max
  The maximum value of the parameter during the run.
• Min
  The minimum value of the parameter during the run.
• Delta
  The difference between the start and end value of the parameter.
• At Line
  The value of the parameter at the crossing of the specified gate line (e.g. Start/Finish).

You can change the displayed parameter, by selecting a parameter from the dropdown menu above.

You can sort the results in ascending or descending order. To do this, you must click on the relevant column to select it and then click on the Sort Ascending or Sort Descending button on the Test Setup ribbon or right-click in the Test Results area and select the option you need.

You can filter the results by right-clicking on a value in the cell results table (e.g. Time (s)). You can then select to include only results with a value equal to the selected value or with a value that is <= than or >= than the selected value for that channel. You can filter multiple channels. A notification bar above the results will shows the applied filters. You can remove the filters by clicking on the X in the notification bar.

You can copy individual results cells so that they can be pasted into other software applications. Click on the relevant cell to select it, right-click on it and select Copy or use the keyboard shortcut. Select multiple cells by clicking and dragging with the mouse or pressing the Ctrl key when selecting cells. Select all cells between 2 cells by holding down the Shift key and between clicking on the first and the second cell.

You can also copy an individual row, column or the entire results table by selecting the required data area, right-clicking and selecting Copy Row, Copy column or Copy All.

You can rename a column by double-clicking on the column title or by selecting the relevant column and right-clicking and selecting Rename Column or pressing F2 on the keyboard. Renamed columns will be included in exported files and generated reports.

Click on the Export button to display a dropdown menu with the export options. You can export the selected results or line results to a .csv or a .txt file. 

You can set the Test Suite software to automatically calculate the Average/Max/Min/Standard Deviation values of all relevant runs by ticking the selection box next to the run number.

Once you have selected more than one result, the average, maximum and minimum values will be displayed. Once you have selected more than two results, it will also display the standard deviation of the selected runs.

If you select the tick box next to the Avg, Test Suite will add a moving average ‘best fit’ curve to all of the selected runs.

If you have specified Interim result(s) in the Test Configuration these will be displayed in the Test Results area. 

The Columns setting will display each interim result as a column on the right-hand side of the results table, in the order it was specified in the settings. If multiple At or Between conditions are met in a run, Test Suite will only display the first result.

The Separate Table setting will display the interim results from a selected run in a new window in the Test Results area. If you select multiple runs, the window will display the interim results from the last selected run. In addition to the interim results, the start conditions will also be displayed.

Change a Channel

You can change the channel used for interim result(s), by selecting the column header for the required result and clicking on the channel name in the Data Column section on  the Test Setup tab or right-clicking on the column header and and selecting the channel name from the dropdown menu. Both options will display a list of all available channels you can replace with.

Add a Channel

You can also add columns to the interim result(s) by selecting a result header and clicking on the Add button in the Data Column section on the Test Setup tab or by right-clicking on the result header and and selecting the Add option from the dropdown menu. Both options will display a list of the available channels you can select to display as a results column associated to that particular interim result.

Remove a Channel

You can remove a column by clicking on the x icon that appears when you hover over the column header.

Click on the Report button in the Test section on the Test Setup tab to see a preview of the report from the session. 

The Report window will present options to print or export the report.

Alternatively, you can right-click in the Test Results area and select Export to either export the results to a .CSV file or export the results to a Text file.

The report will contain the entered session data and test results. 

This Report Chart displays operating vehicle TKPH to be compared against rated tyre TKPH. This Report Chart is completed for front TKPH only.

• Displayed TKPH (i.e. Cycle, Moving Average, Manufacturer Corrections) can be adjusted in Test Configuration.

• Displayed tyres can be adjusted in Session Data.

This Report Chart displays the frequency of Cycle TKPH values to visualise the bulk of Cycle TKPH values and compare between circuits.

This Report Table summarises key information for each circuit and the entire dataset. This is most useful to compare operations between multiple circuits.
