Soil Modeling for Virtual Design and Performance Analysis of Mobility Systems for Off-Road Industry

Prof. Mehari Tekeste I Associate Professor, Agricultural and Biosystems Engineering, Iowa State University

Low-ground pressure (LGP) tires that exhibit higher flexibility than conventional standard radial tires are recently introduced for agricultural machine systems. The LGP tires carry a 20% to 40% larger vertical load than the conventional standard radial tires and appear to create a larger contact area on soft soils, potentially reducing soil compaction and improving traction and crop yield potential. Due to the complex soil-to-tire system between deformable soil and flexible tire elements, it has been challenging to fully leverage the ... Read More

In both cases, DEM has proven itself to be valuable in providing insights and ... Read More

Soft-Soil Mobility Modeling w/ PM-FlexTire, Altair® EDEM™ & MotionSolve®

Doug Louth I Sr. Technology Fellow, Pratt & Miller Engineering & Fabrication, LLC
Kumar Periannan I Technical Expert, Pratt & Miller Engineering & Fabrication, LLC

Soft-Soil Mobility Modeling has lagged behind on-road mobility modeling primarily due to the limitations of available soil and corresponding tire models. Pratt Miller in collaboration with Altair’s EDEM and MotionSolve teams have developed breakthrough soft-soil mobility simulation capability. The coupling of EDEM’s state of the art DEM soil modeling solution and a new flexible, pneumatic, treaded tire model, PM-FlexTire, it is now possible to extend what is possible via virtual development early in the PD process. This limits or avoids ... Read More

Numerical Design and Manufacturing of Lithium-ion Battery Electrodes using Discrete Element Method (DEM) Modelling

Dr. Ruihuan Ge I Faraday Institution Research Fellow, The University of Sheffield

The ever increasing demand for renewable energy worldwide means that developing efficient energy storage techniques are of critical importance. Materials in particulate forms are commonly used in essential energy storage systems, e.g. lithium-ion battery electrodes. In this project, Discrete Element Method (DEM) simulation is used to investigate the calendering process of lithium-ion battery electrodes. By combining DEM, X-ray computed tomography and electrochemical analysis, electrode mechanical and structural properties were investigated. Detailed stress and structural evolutions at microscopic particle scale were ... Read More

Coarse-Grained DEM Simulation of Particle Behavior and Heat Transfer for Large Scale Equipment

Dr. Motoaki Saruwatari I Research Scientist, Computer Aided Engineering and Development, Sumitomo Metal Mining Co LTD., Japan
Hideya Nakamura I Department of Chemical Engineering, Osaka Metropolitan University, Japan

Recent improvements in computer performance have made it possible to simulate the behavior of many particles and heat transfer using the discrete element method (DEM). However, in the case of large scale equipment in industries, simulating particle behavior and heat transfer using DEM is still difficult due to a large number of particles required. To address this issue, we have developed the newly coarse-grained method named the Modified Coarse-grained method for Granular Shear Flow (M-CGSF)[1]. In this study, we conducted ... Read More

Discrete-Element-Simulations in Lithium-Ion Battery Production

Johannes Lindenblatt I Research Associate, Technische Universität München

High-performance and low-cost batteries have become a key feature in various applications, critical for reaching climate protection goals. Battery production requires significant improvements to achieve energy density and cost targets. The battery production process chain comprises many consecutive process steps significantly influenced by the material properties and electrode compositions. Therefore, it is crucial to deeply understand how the production processes affect the battery cell and determine what special requirements the battery production processes must fulfill. By creating Discrete-Element-Simulations, the processes ... Read More

Right Approach for Chute Design-Handling Alternative Fuels in Cement Plants

Kapil Kukreja I Group Manager & Programme Leader - Project Engineering and System Design, National Council for Cement and Building Materials (NCCBM)

The Indian Cement industry is targeting to replace 25% of coal by utilizing Alternative Fuels (AFs) by 2030. However, available AFs in India have different characteristics & properties, and handling multiple types of AFs with a single system is a challenge. Although the technical know-how for AFs material handling equipment is well established now, yet the transfer of material from one equipment to another through a transfer chute may lead to jamming issues if the chute is not designed as ...
