Using Altair EDEM in the Design of Construction and Mining Equipment

This video shows how EDEM can be used to understand and predict the behavior and impact of different bulk materials like gravel, clay, tar and grass on a dump truck. EDEM provides accurate contact forces data that can be used to run finite element analysis using OptiStruct.

EDEM can be used to aid the design process of dump truck bodies. Realistic material modeling allows users to test dump truck performance in different operating conditions by analyzing loading/unloading patterns or pressure distributions.

In this video EDEM is coupled with MotionSolve to better understand and predict the performance of a grab bucket handling different materials. Critical information on how the equipment responds when interacting with the bulk material can be obtained such as force and torque acting on different parts as well as the stress on components.

In this webinar, learn more about EDEM software and how it can be used for the design, performance testing, and optimization of mining and construction equipment.

Dump trucks, excavators, loaders and dozers are all designed to handle bulk materials that can vary in shape and form, from large quarry rocks to cohesive soils or abrasive ores. These materials and their interaction with the machine parts have a strong effect on equipment performance.

EDEM software, powered by the Discrete Element Method (DEM), accurately simulates the behavior of rocks, soils, ores and gravel, etc. It provides engineers with crucial engineering insight into how materials will interact with their equipment during a range of operating conditions and enable them to use realistic loads in Finite Element Analysis and Multi-body Dynamics simulations for optimal designs.

Webinar Contents:
• Challenges of designing heavy equipment
• Introducing EDEM simulation technology: overview, material calibration, and CAE integration
• EDEM applications examples:
dump trucks, excavators, road graders, dozers, loaders, grabs and dragline buckets

This video produced in collaboration with Xuzhou Construction Machinery Group (XCMG) shows how EDEM software can be used to simulate grader applications such as flattening, ditching and scraping. Ground particles can be colored by velocity, layers and position to enable analysis. Additionally, data for the grader blade can be obtained such as wear, pressure and forces allowing equipment optimization.

This eBook discusses the challenges linked to designing equipment intended to handle rocks, soils, ores and gravel. It introduces EDEM -bulk material simulation software- and explains how it can be used for the design, performance testing, and optimization of construction and mining equipment. The following topics are covered: - Challenges of designing heavy equipment handling bulk materials - What is EDEM simulation technology - CAE integration - Benefits of using EDEM simulation as part of the design process - Applications examples: dump trucks, excavators, dozers, loaders, grab buckets, and more - Case study: Increasing the operational performance of a truck load body at VR Steel

EDEM can be used to optimize the design of excavator buckets - providing key insight into equipment performance. Different designs can be compared for handling a range of materials such as rocks, gravels or more cohesive materials. Key information on loading time, spillage and wear can be visualized and analyzed – enabling more design optimization improvements to be made.

Nemag BV is a manufacturer of grabs designed for handling a range of bulk materials from coal and iron ore to grain, animal feed, scrap metal, minerals, and biomass. Nemag worked with the group of Dr. Dingena Schott at Delft University of Technology (TU Delft) to develop a new generation of grabs for iron ore that are faster and lighter — using Altair EDEM™ bulk material simulation software to test and optimize the new design.
