This solution enables engineers designing heavy equipment such as excavators, ploughs and off-road vehicles to introduce realistic bulk material behaviors to their multi-body dynamics simulations — offering unrivalled insight into how material loads are transferred throughout a mechanical system and providing key insights into equipment-material interactions. EDEM is capable of recreating the behavior of a wide range of real-world bulk materials from gravel, sand and rocks; to compressible soils, clays, and highly cohesive ores as well as powders.7 ns 1 answer key
Users can select materials from a library of over 40, ready-to-use materials models or create customized ones to suit specific applications needs. During simulation, the coupling transfers the realistic material loads from EDEM directly into RecurDyn where they are used to calculate the effect on equipment dynamics.Block diagram of optical network
The updated dynamics are then passed back to EDEM to provide realistic force-feedback throughout a simulation. By including high-fidelity loads in their RecurDyn multi-body dynamics simulations engineers do not need to rely on hand calculations or assumptions to represent equipment loads and they get greater confidence in their designs. This also means that extensive what-if analysis can be performed without the need to build expensive prototypes.
Engineers can explore different scenarios and easily compare designs for a range of different materials and different maneuvers early in the design cycle. This provides greater insight into equipment performance and enables more design optimization improvements to be made.
It also gives confidence that equipment will perform as expected in specific conditions. This capability brings greater insight into equipment performance and results in increased design accuracy and reduced prototyping costs. July 30, CAD Exchanger 2. Developed by TeoThemes.

EDEM 2. Discrete Element Method DEM simulation is transforming the business of designing and optimizing equipment for the handling and processing of bulk materials. When used properly, DEM simulation gives you key design information on bulk solid material flow behavior that is very difficult, or even impossible to get using standard test methods or other methods of engineering simulation. First introduced to industry nearly a decade ago, EDEM is powered by state-of-the-art Discrete Element modeling technology and uniquely provides engineers with the capability to quickly and accurately simulate and analyze the behavior of their granular solids systems.
By introducing EDEM simulation and analysis into their design workflow, companies can significantly reduce physical prototyping and testing costs and increase the productivity and reliability of their equipment and processes. EDEM provides the key functionality and performance that customers need to realize maximum productivity benefits from engineering simulation across product design and production processes.
DEM Solutions collaborates closely with leading hardware vendors to maximize the speed and scalability of EDEM software on the new generations of multi-core processors.
Pre-processing tools in EDEM Creator include import of CAD models of equipment and templates of representative model particle shapes, and particle-scale physics models along with built-in particle initialization.EDEM Simulation of Combine Harvester: Screw Auger Systems & Grain Sieving
Specification of the model particle shape and size distribution, along with the mechanical, material and other physical properties, collectively form the model of the bulk material being simulated. These material parameters can be stored in a library allowing you to build a collection specific to your processes. CAD models of real particles can also be imported to obtain an accurate representation of their shape.
Custom properties for particles, contacts, equipment geometry and global variables enable complex models of particle physics and chemistry to be implemented. The EDEM Simulator is the solver that performs the particle-scale physics calculations determining bulk particle dynamics. It is highly parallelized for optimal compute efficiency on multi-core computers.
It is based on a sphere-element particle primitive from which multi-element particles can be generated to represent non-spherical particles, which is the fastest method of simulating non-spherical particles. Post-processing is carried out in the EDEM Analyst using an extensive set of data analysis and 3D visualization tools. Information from the bulk system can easily be extracted and viewed with fast image rendering and video generation as well as data mining and export for further analysis.Discrete element method DEM technology company EDEM has released a new simulation tool that enables engineers to include realistic bulk material loads as standard in Adams system dynamics analysis.
During simulation, the coupling transfers the realistic material loads from EDEM for Adams directly into Adams, where they are used to calculate the effect on equipment dynamics. The updated dynamics are then passed back to EDEM to provide realistic force feedback. When in operation, the performance of heavy equipment is dependent to some degree on the bulk material being handled.
Stresses on load arms, hydraulic forces, the traction of the tires and delivery of power are all impacted by the bulk for material. Understanding how equipment will perform in a specific material environment is critical to ensuring an optimal design that combines strength and durability, with performance efficiency. EDEM for Adams works to address these needs by providing engineers with the capability to simulate bulk materials and use these loads in Adams system dynamics simulations.
Using high-fidelity representations of the loads and forces acting on equipment reduces the need for hand calculations and approximation when designing heavy equipment. It also allows for further optimized equipment design and reduced physical testing.

Introduction Through this introductory tutorial we can learn how to set-up and analyze an EDEM simulation. The exercise is directed at beginners to get a basic understanding of the software.
The model used here is a conveyor belt that transports material to a hopper. The main focus in on:. Creation a Particle Prototype from multiple spheres. The multi-sphere particle shape is defined using particle CAD templates, which can be imported to EDEM and manually filled with spherical particles. Creation of bin groups in the Analyst to analyze particles and their properties in specified regions.
Start EDEM. Select a location on the local machine e. Enter a file name e. Change the following measurement units:. Enter the model title and description The model title and description will appear in the Data Browser window. Click on the Globals tab in the Tabs pane. Enter the title Conveyor Model in the Title field in the Simulation section.
Enter the description in the Description field. Set the contact models The Physics section lists contact models and forces.
