Moving loads library

One project can contain several trajectories and several moving loads. In one trajectory, several moving loads can engage and one moving load can reoccur in several projects.

To keep everything manageable, the moving loads are placed in a library. Click on to open the library.

A moving load can be preceded by the icons or .

• The icon indicates that the moving load is permanently in the library and therefore available in all projects.
• The icon indicates that the moving load is floating in the library and therefore only available in the current project.
  
• With the button , you can define a new moving load. We will run through the parameters/ possibilities of the window:
  
  • Name: the name of the moving load in the library.
  • Length: the total length of the train
  • Number of loads: the number of points (or wheel axles) on which load engages
  • Reference for the load
    • Local coordinate system
    • Global coordinate system
  • Table: the number of rows in the table reflects the number of loads.
    • The position of the loads in relationship to the train can be entered in 2 ways:
      • d₁ is the distance from the end.
      • d₂ is the distance from the beginning.

      When you enter the distance d₁, Diamonds will automatically calculate the distance d₂ as the length of the train minus d₁ and vice versa if you enter the distance d₂.

    • Next you can enter the value of the forces and moments for each load.
  • With the buttons and  you can import or export a moving load.
  • In the example, the window looks like the illustration above.
• Using the button  you can adjust the selected moving load.
• Using the button  you can place a floating moving load permanently in the library. The icon for the moving load will change from to .
• Using the button you can place a permanent moving load in the library as floating. The icon for the moving load will change from to . Diamonds will automatically remove the moving loads that are not allocated to the trajectory.
