Innovative Engineering Software Delivers Missing Link in Equipment Design

•DEM Solutions launches ‘EDEM Add-In for ANSYS Workbench’ allowing detailed insight into the interaction of bulk materials with equipment

•DEM Solutions introduces co-simulation to enhance equipment design in a world first for the FEA sector

•Co-simulation will enable engineers to design bulk material handling equipment with confidence to be ready to face the most challenging environments



30 September 2014, Edinburgh, Scotland - DEM Solutions, the Discrete Element Method specialist – has developed and launched a co-simulation capability that could revolutionise how engineers approach the design of equipment that handles bulk materials.

DEM Solutions has worked with ANSYS, a global leader and innovator of engineering simulation software, to develop a co-simulation capability enabling engineers to access EDEM® bulk materials simulation data directly within ANSYS® Workbench™, allowing high-quality representations of bulk materials and their complex behaviour to be included in Finite Element Analysis (FEA). The new ‘EDEM Add-In for ANSYS Workbench’ introduces a streamlined process to transfer material load data and will give equipment designers and manufacturers access to EDEM data in the familiar Workbench environment.

The major benefit of the new capability is that it removes any guesswork by giving design engineers the data on the pressures and forces caused by the bulk materials acting on the equipment – this insight has previously not been available.

Manufacturers of equipment designed to handle bulk materials, such as bucket loaders, transfer chutes and truck bodies must take into consideration the behaviour of materials such as coal, ores or soil. Previously, this has been complex and difficult to predict using traditional methods and estimating the effect of material loads on equipment can significantly impact the success of the product design.

To gain insight into the structural integrity of any proposed design, engineers routinely use CAE tools such as FEA. This approach can be relied upon to provide accurate analysis of the structure; however, the effect of interaction between the structure and bulk material which the equipment is designed to handle is a significant approximation which can only be confirmed by time-consuming and expensive physical prototype testing to ensure the design meets requirements.

EDEM gives realistic bulk material data for the load acting on an excavator bucket.

This load is then transferred into ANSYS® Mechanical™ and used in structural FEA analysis of the bucket and boom arm.





Shane Moeykens, Senior Partnerships Manager of ANSYS said:

“This development will complete the picture for design engineers in providing a detailed understanding of the effect of materials on equipment design, allowing improved design accuracy and greater insight into equipment performance. In addition, the cost of expensive physical prototyping and days of reliance on assumption and guesswork will be reduced. By coupling EDEM with our ANSYS Workbench, equipment designers can access multiple tools in a quick and easy environment.”

Richard LaRoche, DEM Solutions VP of Engineering & Software Development added:

“This innovation has been driven by customer demand and streamlines the integration of the simulation data. DEM Solutions is delighted to work with ANSYS to bring this innovative software development to the international CAE community. In line with our collaborative approach, we wish to work with partners to create and enhance co-simulation solutions to allow equipment design engineers to be more productive and create better designs. The new EDEM-ANSYS co-simulation will allow the design and delivery of equipment with renewed confidence and certainty.”

Missing Link Indeed Or Perhaps?

Any advance along these lines is most welcome and the joint effort of EDEM and ANSYS is to be lauded.

Whatever the traditional inertia against newer technology it must be appreciated that imperfections persist, are largely insignificant and immeasurably better than preceding tools.

When the article, as clicked, mentions the application in context to mobile plant and stockyard machinery I, for just one, wonder how accurate the estimation of digging force can be.

There is plenty of literature about digging and break-out force relating to mobile shovels but precious little complimentary literature about bucket wheel reclaimers and the like. For the latter there were, as I recall, only 2 published values of digging resistance previously available. This gave a tremendous comfort level to reclaimer manufacturers who gladly shared their ignorance with their clientele. I have yet to meet any manufacturer or client who could, or would, tell me what their cutting resistance might be etc etc.

Now, if it is possible to evaluates digging resistance with this software add-in, the field is wide open for other manufacturers to offer better, lighter and cheaper machines: all within the same commercial software package:

even with the regular update hassles for which the parent software house is rather well known. ■
