Assembly Modeling with ANSYS

In my previous article, I wrote about how you get what you pay for with your analysis package.  Well, buckle up for some more…but this time we’ll just focus on handling assemblies in your structural/thermal simulations.  If all you’re working on are single components, count yourself lucky.  Almost every simulation deals with one part interacting with another.  You can simplify your boundary conditions a bit to make it equivalent, but if you have significant bearing stresses, misalignments, etc…you need to include the supporting parts.  Better hope your analysis package can handle contact…

Image result for get what you pay for

First off, contact isn’t just for structural simulations.  Contact allows you to pass loads across difference meshes, meaning you don’t need to create a conformal mesh between two parts in order to simulate something.  Here’s a quick listing on the degrees of freedom supported in ANSYS (don’t worry…you don’t need to know how to set these options as ANSYS does it for you when you’re in Workbench):

image

You can use contact for structural, thermal, electrical, porous domain, diffusion, or any combination of those.  The rest of this article is going to focus on the structural side of things, but realize that the same concepts apply to essentially any analysis you can do within ANSYS Mechanical..

First, it’s incredibly easy to create contact in your assembly.  Mechanical automatically looks for surfaces within a certain distance from one another and builds contact.  You can further customize the automated process by defining your own connection groups, as I previous wrote about.  These connection groups can create contact between faces, edges, solids bodies, shell bodies, and line bodies.

image

Second, not only can you create contact to transfer loads across different parts, but you can also automatically create joints to simulate linkages or ‘linearize’ complicated contacts (e.g. cylindrical-to-cylindrical contact for pin joints).  With these joints you can also specify stops and locks to simulate other components not explicitly modeled.  If you want to really model a threaded connection you can specify the pitch diameter and actually ‘turn’ your screw to properly develop the shear stress under the bolt head for a bolted joint simulation without actually needing to model the physical threads (this can also be done using contact geometry corrections)

image Look ma, no threads (modeled)!

image

If you’re *just* defining contact between two surfaces, there’s a lot you simulate.  The default behavior is to bond the surfaces together, essentially weld them closed to transmit tensile and compressive loads.  You also have the ability to let the surfaces move relative to each other by defining frictionless, frictional, rough (infinite coefficient of friction), or no-separation (surfaces don’t transmit shear load but will not separate).

image

Some other ‘fancy’ things you can do with contact is simulate delamination by specifying adhesive properties (type I, II, or III modes of failure).  You can add a wear model to capture surface degradation due to normal stress and tangential velocity of your moving surfaces.  You can simulate a critical bonding temperature by specifying at what temperature your contacts ‘stick’ together instead of slide.  You can specify a ‘wetted’ contact region and see if the applied fluid pressure (not actually solving a CFD simulation, just applying a pressure to open areas of the contact interface) causes your seal to open up.

image

Now, it’s one thing to be able to simulate all of these behaviors.  The reason you’re running a finite element simulation is you need to make some kind of engineering judgement.  You need to know how the force/heat/etc transfers through your assembly.  Within Mechanical you can easily look at the force for each contact pair by dragging/dropping the connection object (contact or joint) into the solution.  This will automatically create a reaction probe to tell you the forces/moments going through that interface.  You can create detailed contour plots of the contact status, pressure, sliding distance, gap, or penetration (depending on formulation used).

image

image

Again, you can generate all of that information for contact between surface-to-surface, surface-to-edge, or edge-to-edge.  This allows you to use solids, shells, beams, or any combination you want, for any physics you want, to simulate essentially any real-world application.  No need to buy additional modules, pay for special solvers, fight through meshing issues by trying to ‘fake’ an assembly through a conformal mesh.  Just import the geometry, simplify as necessary (SpaceClaim is pretty awesome if you haven’t heard), and simulate it.)

PADT Startup Spotlight – The Speed of Simulation

The Speed of Simulation  with Velox Motorsports

With thoroughly engineered components including the use of Finite Element Analysis (FEA), thermodynamics, heat transfer, and Computational Fluid Dynamics (CFD), PADT Startup Spotlight Velox Motorsports strives to produce aftermarket parts that can effectively outperform the factory components.

Join Velox Co-Owners Eric Hazen and Paul Lucas for a discussion on what they use ANSYS simulation software for and how they have benefited from it’s introduction into their manufacturing process.

This webinar will focus on two projects within which the engineers at Velox have see the impact of ANSYS, including:

Using Finite Element Analysis (FEA) to reverse engineer a Subaru fork, find the cause of failure and develop an improved replacement part.

Using Computational Fluid Dynamics (CFD) to rub a shape sensitivity study on Nissan GT R strakes, and develop a replacement that increases down-force without significantly increasing drag.

ANSYS 18 – SpaceClaim Webinar

In its latest release, ANSYS SpaceClaim further integrates its ease of use and rapid geometry manipulation capabilities into common simulation workflows. From large changes to behind the scenes enhancements, you’ll notice efficiency improvements across the board. You’ll save time automating geometry tasks with the expanded recording and replay capabilities of SpaceClaim’s enhanced scripting environment.

Join PADT’s Application Engineer Tyler Smith  for this webinar and learn about several improvements that are guaranteed to save time, enhance your designs and improve overall usability. We’ll cover:

  • Continued development of SpaceClaim’s scripting environment. With expanded recording capabilities and replayability of scripts on model versions, you’ll save time in the steps needed to automate geometry tasks.

  • Faceted data optimization and smoothing enhancements. You can greatly simplify and smooth topology optimized STL data for downstream printing, while preserving the integrity of localized regions.

  • Lattice Infilling for additive manufacturing. The Infilling functionality has greatly expanded to include several lattice infill types, all with custom options to ensure your 3-D printed component has an ideal strength-to-weight relationship.

  • Exploration of inner details of a model with the new fly-through capability. Without hiding components or using cross sections, this capability provides graphical feedback at your fingertips while making it even more enjoyable to work in a 3-D environment.

Increase your throughput and reduce manufacturing costs

Fast, easy to use lightweighting for structural analysis is now only a few clicks away thanks to the introduction of Topology Optimization in ANSYS 18.

Engineers who use Finite Element Analysis (FEA) can reduce weight, materials, and cost without switching tools or environments. Along with this, Topology Optimization frees designers from constraints or preconceptions, helping to produce the best shape to fulfill their project’s requirements.

Topology Optimization also works hand-in-hand with Additive Manufacturing; a form of 3D printing where parts are designed, validated, and then produced by adding layers of material until the full piece is formed. Pairing the two simply allows users to carry out the trend of more efficient manufacturing through the entirety of their process.

Join PADT’s simulation support manager Ted Harris for a live presentation on the full
benefits of introducing Topology Optimization into your manufacturing process. This webinar will cover:

  • A brief introduction into the background of Topology Optimization and Additive Manufacturing, along with an overview of it’s capabilities

  • An explanation of the features available within this tool and a run through of it’s user interface and overall usage

  • An in-depth look at some of the intricacies involved with using the tool as well as the effectiveness of it’s design workflow
