No More Guessing! – Enhanced Design Insight Using the EDEM-Adams Coupling

In this final blog of our Adams-EDEM co-simulation series, Darren Simoni from DSIM Technologies explains how EDEM and Adams have been used during the design of a skid-steer loader to increase the accuracy of system level simulation using less time and effort than traditional load estimation methods.

Dig the Dirt! – Application Examples using Adams-EDEM Co-Simulation

In my previous blogs I introduced the Adams-EDEM coupling, and explained how it works. In this post I want to share with you two examples of the Adams-EDEM coupling in action!

Rigorous, Transient 3D CFD Models of Unusually Complicated Fluid Networks/Circuits

The role of fluid dynamics simulation in the design and development of various products has recently undergone what is arguably a paradigm shift due to the ability to simulate unusually complicated, multi-component, hydraulics flow circuits using three dimensional (3D) computational fluid dynamics (CFD) models.  The example shows a lubrication system model (developed using the Simerics-Sys / PumpLinx CFD software) for a 16 cylinder reciprocating internal combustion engine.  This represents an advance in system-level modeling of hydraulic fluid networks over the current state of the art which is a blend of zero and one-dimensional models.  This also represents continued progress in the role of CFD from the traditional component level modeling to system level modeling.  System level modeling provides insight into interactions between components.  Finally, it is equally important that model setup and run times are reasonable relative to development time scales.

Get Your Hands Dirty! – How to Run An Adams-EDEM Co-Simulation

In my previous blog post I introduced the Adams-EDEM coupling that allows engineers to realistically simulate how bulk materials interact with their systems dynamics. In this post I want to give some insight on the workflow needed to use the coupling.

Reducing the Product Development Time of a Rotary Cutter System Through Simulation

In the agricultural and heavy machinery industries, durability and strength are some of the most important indicators of quality. Maintaining high levels in these areas requires the application of many different tests and assessments to the end product. However, one of the most time-consuming parts of the production is the lengthy process of building physical prototypes, testing them for durability, then redesigning several parts and starting all over again. This process can significantly extend the time it takes to get a product to market. This was the case for John Deere Welland Works while developing a 20-foot rotary cutter system.

Where’s the Dirt? – Use Realistic Material Loads in Adams

The world of heavy equipment is full of big machinery digging and moving dirt. Millions of tons of bulk material are moved every day by excavators, bull dozers, ploughs and trucks. The challenge faced by engineers who are designing such equipment is to understand how their machines will perform in the material environment they operate in.
