Bulldozer Simulation

Simulate your earthmoving by bulldozers

This module simulates a complex Dozing operation by breaking it into Dozing Regions. Each Dozing Region has a single overall direction of push by the Dozer. A preliminary Transport Analysis calculation can be carried out to help users set up optimal Dozing Regions. Dozer productivity is calculated using standard rim-pull curves that can be scaled by the user. Intermediate dozing surfaces are calculated to guide the operation of the Bulldozer from the initial (current) terrain shape to a final shape that is input by the user. These intermediate surfaces are optimized to maximize Dozer productivity.

Maximize productivity

Regions and surfaces
- 3d-Dig Bulldozer performs a fully three-dimensional simulation of the dozer operation. The simulation starts with the pre-dozing surface and the user imports or generates a final target surface for the dozing operation. The system then simulates the excavation and dumping of the dozer operation on an incremental basis. Increments are generated longitudinally using automatic dozing regions and vertically using automatic surfaces. For each increment the dozers path is determined and speeds and productivity derived from the bulldozers speed versus rimpull curve.
Parameters and productivity
- Many parameters can be rapidly varied such as dozing angles, pivot/bridge geometry as well as final target surface. On completion the simulation reports the following:
- Overall prime volume.
- Overall rehandle volume.
- Total execution time.
- Bulldozer productivity.
- Any areas with insufficient spoil room.
Important effects
- As the system is fully three-dimensional, important effects such as longitudinal spoil movement between regions and localised spoil conditions based on pre-dozing topography are correctly taken into account by the simulation.
- Once a simulations is set up the user can rapidly change the dozer target (design) surface. This change can involve either increasing or decreasing the elevation of the surface or substantially changing its geometry.
