HI. Digitising Trucks with Electric drive

This page provides a step-by-step guide on how to create a digitized electric truck on the example of BELAZ 75307 model.

Prerequisites

First of all, you will need to find and download the manufacturer's data sheet/specifications for the required truck model.

The specification must include the following data:

• Weight:

  • Empty (unladen) weight;

  • Maximum payload capacity (payload);

  • Gross weight.

• Truck weight distribution on axles, %:

  • front/rear,

  • unladen/laden.

• Towing and Braking performance.

• Fuel consumption, if applicable.

Creating new project

1. Run Haul Infinity version 22.1 or newer.

Open

Haul Infinity > Version 22.1 > Start button

2. In the upper tab bar, click the Tools button and select the "Truck Creator" option.

Open

Haul Infinity > Tools > Truck Creator

3. In the dialog window that opens, select Create New Project if you want to create a new project, or Open Existing Project to open an existing one.

When you create a new project, it will be automatically named "Project1".

• Save the new project as a file with the suitable name and click Save. The saved file will have an extension ".trucks".

Import Specification

In the first setup step PDF Import, select the PDF file of the downloaded specification/technical sheet for the desired truck. To do this, click the blue plus icon and specify where the downloaded specification is saved.

• If the information you need is gathered in multiple specifications instead of just one, you can upload several PDFs.

• If you need to modify/update uploaded specifications, it is not recommended to delete/add new file, as it causes all the settings to be lost. For this purpose, it is better to use the green re-load button and re-import the corresponding specification.

Adding Regions

In the Regions section add a required number of regions to attach to the truck file for further references, such as:

• Cover Page or Source.

• Weights data.

  • Weight Definitions, if applicable.

• Rimpull chart.

• Retard chart(s).

• Fuel data, if applicable.

Adding Cover page

To facilitate finding information, or when loading multiple specifications, you will find it helpful to add a region of the entire first cover page. To do this:

1. In the Regions panel, click the blue plus icon to add a new region.

2. The Select Region window will open. Select the desired part (in this example, the entire cover page) by simply box-selecting it.

3. Press OK to confirm.

4. The selected area will be added to the Regions list.

• Rename it accordingly.

• Since the Cover page is not a chart, don't check the Chart box.

• If you want to edit the selected region, use the edit/update button (green arrow).

Adding Weights data

1. In the Regions panel, click the blue plus icon to add a new region.

2. The Select Region window will open. Find the section with the weight data and box-select it.

3. Press OK to confirm.

4. The selected area will be added to the Regions list.

• Rename it accordingly.

• Since it is not a chart, don't check the Chart box.

• If you want to edit the selected region, use the edit/update button (green arrow).

Adding Rimpull data

1. In the Regions panel, click the blue plus icon to add a new region.

2. The Select Region window will open. Find the section with the rimpull data and box-select it.

3. Press OK to confirm.

4. The selected area will be added to the Regions list.

• Rename it accordingly.

• Since it is a chart, check the Chart box.

• If you want to edit the selected region, use the edit/update button (green arrow).

Adding Braking data

1. In the Regions panel, click the blue plus icon to add a new region.

2. The Select Region window will open. Find the section with the rimpull data and box-select it.

3. Press OK to confirm.

4. The selected area will be added to the Regions list.

• Rename it accordingly.

• Since it is a chart, check the Chart box.

• If you want to edit the selected region, use the edit/update button (green arrow).

Note

Various editing options are available in the Select Region window via right-click, such as the Select, Drag and Drop, Zoom tools, Return to Previous View, Rotate (clockwise or counterclockwise), as well as Print, Search through the document, Select the entire area, and Display document properties.

Once you have finished adding all the applicable regions, click the Play button to proceed to the next setup step.

Truck Settings

In the Trucks Settings step, specify the applicable data sheets and, if necessary for reference, add the appropriate regions created in the previous step PDF Import.

Truck Information

Populate the applicable Truck information

Units

Check and, if necessary, adjust the suggested units of measurement to match those used in your operation.

Technical Information

Enter the applicable technical information for the truck.

Once you have finished entering all the applicable data, click the Play button to proceed to the next setup step.

Lists

In the Lists step, set the applicable list types (curves, number of gears, axles), which will be used in the following steps (namely Curves and Truck Configurations).

Use the top toolbar buttons to move records up or down the list, sort in ascending or descending order, as well as copy and paste to/from Excel and clear data.

Once you have finished entering all the applicable data, click the Play button to proceed to the next setup step.

Axles Setup

In the Axles Setup step, enter the applicable load distribution data for the axles.

Enter the load distribution parameters in the top Axle Properties panel.

Depending on what data you have, you can choose to edit the data by weight or by percentage (Edit Weight or Edit Percentage columns, respectively).

To facilitate the information search, import the Weight data region added in the PDF Import step.

Locate the applicable information in the image of the weight data region and enter it in the Axles Properties table. In this example, the manufacturer's specification shows distribution by percentage, so check the Edit Percentage box and enter the data as shown. Note that the data for kg in the Empty Weight and Full Weight columns will be calculated and filled in automatically

Specify which axle is driven and the number of tyres.

Once you have finished entering all the applicable data, click the Play button to proceed to the next setup step.

Curves

In the Curves step the imported characteristic curves are digitized.

Because the Rimpull and Braking regions were marked as Charts in the PDF Import Setup step, they will be listed as Curves in the Curves step.

1. For each of the curves listed, select the relevant region from the Region dropdown list.

2. Digitize each curve by the X and Y axes.

• In the X-Axis field, click the Edit button to open the Edit Axes dialog.

• Select the type of chart: Banded or Logarithmic.

• Specify the Lower and Upper values for the axis and select the applicable Units according to the chart.

• Move the axis bar (in this case, the pink line) so that it coincides exactly with the bottom line of the chart (Travel speed, km).

• Press OK to confirm changes.

• Repeat the same procedure to match the red line to the Y-axis (Towing force on wheels).

3. Digitize the Towing performance curve:

• Place the first point on the intersection of the Y-axis with the curve. Try to keep value in the column X (km/h) as 0.00.

• Put the intermediate points all along the curve.

• Use the scroll wheel to zoom in.

• You can move the points by holding down the left mouse button.

• Right-click on a point to delete it.

• Coordinates of points can be entered manually.

• Points can be copied to clipboard and pasted from Excel.

4. Follow the same procedure to digitize the rest of the charts (in this example, Braking performance chart).

Once you have completed digitizing all the charts, click the Play button to proceed to the next setup step.

Truck Configurations

In the last step, Truck Configurations, make the final adjustments to the digitized truck and export both the current configuration and the finished file for use in Haul Infinity.

1. Click the blue plus icon to add a new configuration.

2. In the Name column, enter the name of the dump truck.

3. In the Rimpull Curve column, select the Rimpull Curve chart.

4. In the Rimpull Curve (Trolley Assist) column, select the Rimpull Curve chart when using a trolley drive. This is not applicable for this project, so select "(none)".

5. In the Retard Curve column, select the braking performance chart.

6. In the Fuel Curve column, select the fuel consumption chart. This is not applicable in this project, so select "(none)".

7. In the Active column, tick the checkbox if you want this configuration to appear as active in Haul Infinity.

Saving and exporting

To save your current project at any setup step select File > Save or File > Save As. The project will be saved in ".truck" format.

To export the finished truck file:

• In the Truck Configuration step, click Export Selected Configuration. Specify the path to the folder where you want to save it. The file will be saved in ".opentruck2" format.

• After you have confirmed all the setup steps, the Truck file can also be exported via File > Export OpenTruck. The file will be saved in ".opentruck2" format.

Importing into Haul Infinity

The ".opentruck2" file you have created can be imported into Haul Infinity in the Trucks > Models setup step.

1. Go to Haul Infinity > Setup tab > Trucks>Models step > Add Truck > Import Trucks from Files > specify the path > import the ".opentruck2" file.

Note that if you need to change points, you can do this by copying the data, modifying it in Excel, and pasting it back into Haul Infinity.
