How to Analyze the structural strength of dump truck body during loading and unloading using EDEM +OS one-way coupling
Files used in this example can be downloaded here: DumpTruck_Example_Files.zip
A dump truck is used for transporting materials such as gravel, coal, rock, dirt, etc. A typical dump truck consists of an open bed connected to the rear end of the cabin. A truck body equipped with hydraulic rams to unload the material.
Truck bodies typically need to load and unload material quickly and without spillage to help with productivity. Any material remaining after unloading negatively impacts the truck fuel efficiency as this material has to then be carried around for the next cycle.
EDEM can be used to:
Step-1: Setup Material Model
To select a Material Model either selecting a material from one of the EDEM databases or material must be performed. In this example, calibration is not demonstrated, however, those who want to explore calibration please follow the below links.
In this example, the material model was chosen from the GEMM database by giving 3 simple inputs such as:
Step-2: CAD Model
EDEM supports a wide variety of CAD formats such as Catia, Solid Works, NX, and ProE and neutral files such as STEP, Parasolid, IGES etc.
Geometries are imported to EDEM via the Creator > Geometries > Import Geometry
To run EDEM +FEA analysis the mesh of the part/component to which force mapping is to be carried out should be the same in both EDEM and the FEA package used (Opti Struct)
In this exercise truck body is the major focus of studying structural strength hence using Altair® Hyper Mesh® truck body is meshed and exported as a stl file.
Please refer to the below links to learn about meshing.
Step-3: Introduce Material
To create a bulk material volume packing option chosen in this example. To learn more about Factories in EDEM, watch this brief video tutorial:
Step-4: Define Kinematics
Step-5: Run Simulation
Step-6: Force Mapping and FE Simulation
