Meshparts has been specially developed for the FE-simulation of machines

The finite element modeling of machine tools, handling systems or robots with standard FE software is much more difficult and time-consuming than it should be.

Our FE-software with integrated FE Model Kit has been specifically designed for the efficient modeling of large finite element assemblies. For the often repetitive FE models, such as the drive train, you can use our extensive parametric FE model library.

The combined use of our software and model library offers a very successful solution for the FE simulation of large assemblies with Ansys® and Abaqus®.

Your FEA software has not been designed for this

If you already use a FEA software, then it is probably Ansys®, Abaqus®, Nastran® or Permas®. Or some CAD integrated solution such as ProMechanica® or SolidWorks® Simulation.

If you compute large CAD assemblies (multi-axis machine tools, handling systems or robots) with one of the standard FEA software, you will have already noticed: The software was not really designed for that purpose.

Computing a large CAD assembly with a standard FEA software is highly inefficient. That is actually the reason why the vast majority of machine manufacturers don’t use FEA software in the development stage: too expensive, much too time-consuming, low significance.

Where is the problem?

Why is the finite element analysis of machine tools, handling systems and robots so complicated and difficult?

A machine (tool) or a robot is a complex mechatronic system which consists not only of cast parts or welded structures. About 90% of all components in a machine tool are standardized purchased parts:

  • Linear Guides
  • Ballscrews
  • Servo drives
  • Planetary gears
  • Couplings
  • Toothed belt systems

all these being complex systems with complex structural behavior.

They may indeed be occasionally simulated on individual basis, but the actual task is there to simplify modeling so that the entire machine is efficiently computable. However, such simplifications should not impair the accuracy, validity and reliability of the model.

Therein lies the challenge and the modeling effort: It is precisely these complex machine components that cannot be imported from the CAD system into the FEA system. The existing CAD models were obviously not designed to support this task.

What is the state of the art? Unfortunately, all too often the powertrains in the FEA are either completely ignored or simplified so that the resulting FE model is suitable for static simulations at its best. Very few manufacturing companies do simulate and even fewer of them are capable of detailing the powertrain of their machines.

Discover untapped potential

In the standardization of the FE models lies a huge untapped potential. Remember? 90% of all available components are standardized components. Why not transfer this standardization into the FEA world? After all, you can no longer imagine to construct your purchased parts over and over again.

Imagine you have a machine containing several Wittenstein® gears. Let’s say the linear guides are made by Schneeberger® with ballscrews by Steinmeyer®.

Furthermore, imagine you could find for these components ready-to-use finite element models already containing all relevant simplifications and properties. No catalog search anymore, no search for rigidity curves anymore. Just snap a mouse, click in your model and you're done. Wouldn’t it be great?

The first finite element model library

We grew tired of having to re-model the same FE models - despite their great similarity – all over again. This was the starting point for Meshparts.

We have developed a new technology that allows you to generate any desired number of fully automated, parametric FE models. In other words, we’ve built the very first finite element model library in history.

The FE models in the library are based on Excel® configuration tables, APDL scripts, and the Ansys® robust meshing technology.

Excel® configuration tables allow an easy extension of the FE library. The unique Ansys® programming makes it possible to produce hundreds to thousands of different, fully automated FE models with various parameterization based on a single APDL script. The robust meshing technology of Ansys® ensures that automatically generated FE models are always provided with an optimal finite element mesh.

Configuring instead of modeling

Once you have an extensive finite element model library that maps all variations of your products, you do not have to model anymore. It’s just enough to configure. And configuring is - as you already know from the CAD world – by far more efficient than modeling.

If your machine contains 90 % or more of very similar or even identical components while only the configuration does change, then you don’t have to ever model again FE models.

We have developed a software and a library that in combined use allow for the first time a parametric and component-based finite element modeling.

Finite element models can be automatically parameterized and positioned as desired. You get access to validated simulation models so that you are able to build them easily in your finite element assemblies. Any change or re-use of complex FE assemblies is only a few clicks away. Changes to any given component do not request modifying the whole assembly.

We do not want you to give up your existing FEA software. With our software, you are able to generate clean Ansys®- and Abaqus® models. Thus, you can compute the FE solution either with Ansys or Abaqus.

Time and again there may be some individual FE models where manual modeling is unfortunately the only remaining option. Such models you can create as usual with Ansys®, add them to your Meshparts FE library and then assemble them with other components in the Meshparts software.

Faster in the conceptual design phase

The conceptual design phase doesn’t usually require detailed geometries. A rough, bulky structure is often sufficient.

Despite all the simplifications the models are able to represent their function correctly.

Therefore, in the conceptual design phase it makes little sense to go through the whole design analysis cycle. Most models (e.g. drive trains) cannot be transferred from the CAD into the FEA system. The importable parts are so simple (mostly blocks), that they can also be modeled directly in the FEA system.

Using the freely available Meshparts FE Model Kit, you can work in the conceptual design phase with the Meshparts software usually without the CAD interface. This saves a surprising amount of time. The video on the left shows a simple example of how the CAD-free modeling in the conceptual design phase works.

Through the consistent use of ready-to-use FE models, machine variants can be tested with Meshparts very fast before they are fully constructed.
