建築和採礦設備
滑移裝載機、挖掘機、挖掘裝載機和卡車車身都用於處理形狀和形態各異的散裝材料，從大型採石場的岩石到黏性土壤、磨料礦石或自由流動的顆粒。 這些材料及其與機器元件的交互作用對設備效能有很大影響。 EDEM 允許工程師預測散裝材料的行為，並識別堵塞、溢出和易磨損區域的風險。 其提供精確的材料載荷，以用於有限元分析 (FEA) 和多體動力學 (MBD) 模擬最佳化設計。
農業機械
拖拉機、聯合收割機和牧草收割機都用於處理各種顆粒材料，如農作物、種子和土壤，這些材料的性質因位置和季節條件而有所不同。 這些材料可變性對機器效能有很大影響。 EDEM 可以預測這些材料的流動，並識別堵塞、磨損和作物損壞的風險。 其可以與 Altair® MotionSolve® 等多體動力學工具相結合，模擬作物 - 機械、土壤 - 機械的交互作用，並預測設備對各種材料的反應。
越野車輛
越野車面對著世界上一些最具挑戰性的環境，包括沙子自由流動的沙漠到碎石土路和黏稠的泥濘道路。 EDEM 可以逼真地模擬各種地形，包括軟土、乾砂以及崎嶇的礫石表面等。 當與 MotionSolve 等多體動力學相結合時，其可為車輛機動模擬提供極大的真實感，使工程師能夠預測履帶式和輪式車輛在各種環境中的行為和效能，並研究在現實世界中無法輕易複製的複雜動作。 讓工程師能在設計早期執行廣泛的假設設計分析，以減少對物理樣機和測試的依賴性並節省相關成本。

Pharmaceutical Powder Process Modeling using the Discrete Element Method (DEM)
In this technical webinar hosted in collaboration with the Center for Structured Organic Particulate Systems (C-SOPS) at Rutgers University, experts will discuss how DEM can be used to better understand powders and optimize pharmaceutical manufacturing processes. The focus will be on 3 main questions and areas: - What is the residence time distribution of particle blends? - How to study powder properties changes due to shear? - How to understand API agglomeration in continuous powder flow? Presentations will also cover examples of applications of Altair EDEM software and techniques for calibrating powders.
From Mine to Blast Furnace – Optimizing the Steelmaking Process with EDEM
In this webinar learn more about EDEM software and how it can be used to optimize a range of operations and processes as part of the steelmaking process.
Bulk materials such as iron ore, coal, pellets and sinter are at the core of the steelmaking process. From transporting raw materials from the mines to the plant by wagons, moving materials on conveyor belts to the blast furnace and the actual charging of the furnace, efficient handling and processing of those materials is critical to achieve efficiency.
EDEM software, powered by the Discrete Element Method (DEM), accurately simulates the behavior of rocks, soils, ores, gravel, etc. It provides engineers with crucial insight into how bulk materials will interact with their equipment during a range of operation and process conditions.
Webinar Contents:
• Raw material handling and transportation:
improving performance and reliability of equipment such as transfer chutes, coal wagons, bucket elevators, screw augers and more.
• Processes: optimizing performance of machines such as cone crushers, mills, vibrating screens, dryers and mixers.
