Detailed Descriptions of the Introduction to ANSYS Mechanical Course Workshops
DRD Workshop 1 - Static Stress Analysis of a Fluid Connector
In this workshop we expose the user to the ANSYS Workbench and Mechanical interfaces and perform a simple static stress analysis on the fluid connector. Basic file management is discussed as well.
DRD Workshop 2a - Element Types and Physical Behavior
This workshop demonstrates how to control creation of lower order versus higher order elements and tetrahedron versus brick elements in Mechanical. It also provides students the opportunity to compare solution accuracy and computational resources for models with lower and higher elements using the Mechanical solution information object.
DRD Workshops 2b - 2h. Mesh Controls on a Casting
This set of workshops demonstrate how to use some of the meshing techniques available in Mechanical to obtain accurate stresses with pinch controls, Multizone, Inflation, and Sphere of Influence methods .
DRD Workshop 3- Assigning Material Properties to Parts in Oilfield Pump Assembly
This workshop uses various WB techniques to assign material properties. The WB Engineering Data Module is discussed in detail.
DRD Workshop 4 - Stress Analysis of a Pump Fluid End WIth Multiple Load Condiitons
This workshop exposes all of the various structural loading options available within Mechanical.
DRD Workshop 5 - Stress Analysis of a Pump Fluid End Using Direct and Iterative Solvers
We start the solution with an assembly and suppress all of the parts, except one for analysis. We use mapped meshing to set up the mesh. We use solution options to control which solver Mechanical uses for a static solution, direct or iterative. We use the solution information object to monitor the solution and to determine which solver is faster. For the iterative solve we use a preprocessing command object to set the solution accuracy. We turn the weak spring option off and on to determine the effect of weak springs on the solution.
DRD Workshop 6a - Stress Analysis of a Flanged Tube and Check of Results
The primary purpose of this workshop is to provide students the opportunity to check the results of the finite element model using hand calculations based on closed form solutions. We use symmetry boundary conditions to perform analysis on a quarter model of the flanged tube. We define a local cylindrical coordinate system and then use it to calculate axial, radial, and hoop component stresses. Finally, we compare the finite element model component stresses with stresses calculated using closed form equations for thin and thick walled pressure vessels. Students discuss with the instructor the correlation between the finite element and hand calculated stresses.
DRD Workshop 6b - Postprocessing Options, Introduction to Scoping and Convergence
This workshop covers the extensive options available for results post-processing within ANSYS Mechanical including cut planes, vector plots, legend manipulation, result display scaling, etc. We also get a first look at scoping of results and cover the concept of mesh convergence.
DRD Workshop 7 - Stress Analysis of a Mechanical Link Using Scoping and Convergence
The focus of this workshop is use of scoping and convergence to evaluate local stresses. We start the workshop by doing stress analysis on a version of the link, which has a sharp corner, and students refine the mesh at the sharp corner to discover first hand the behavior of a stress singularity. Using model branching students add to the project a version of the link, which has a fillet where the sharp corner was present in the previous version. Students define a scoped stress object for stresses in the fillet and then use convergence to determine the stress to an accuracy of 2%.
DRD Workshop 8 - Stress Analysis of a Platform Assembly
This workshop is designed to provide students with practice modeling assemblies. We read the assembly into Mechanical and perform static stress analysis using default bonded contact to hold the parts together. We then use model branching to make a new version of the model, which has no separation contact instead of bonded contact for some of the connections, and we compare the behavior of the models with bonded and no separation contact in the connections.
DRD Workshop 9 - Modal Analysis of an Alternator Bracket with and without Prestress
In this workshop we set up a model of an alternator bracket for normal modes analysis. We model the alternator attached to the bracket as a rigid point mass and monitor the change in natural frequencies and mode shapes as we change it to a deformable point mass. We also add standard earth gravity and note that Mechanical takes into account prestress effects if structural loads are present while performing a normal modes analysis.
DRD Workshop 10 - Stress Analysis of a Pipe and Plate Assembly with Rigid Body Motion
This workshop teaches the user to identify and fix locations in a model that may have rigid body motion due to contact regions that are not correctly defined. We also show the usefullness of a Modal analysis in determining rigid body motion in a static model; rigid body motion causes zero frequency modes in a normal modes analysis.
DRD Workshop 11 - CAD Parameter Associativity of a Piston
The purpose of this workshop is to demonstrate associativity between CAD software, Workbench, DesignModeler and Mechanical. The starting point for this workshop is a parametric model in DesignModeler format. DesignModeler functions as the 'CAD' system for this workshop; the same principles apply to CAD packages. We transfer the model to ANSYS Mechanical, set up and solve the model in a simple stress analysis. We then make changes to the geometry using DesignModeler, update the model in Mechanical and re-solve. We demonstrate the usefullness of the Design of Experiments functionality within Workbench.
DRD Workshop 12a - Analysis of a Sheetmetal Pan Including Corner Spot Welds and Edge to Edge Contact
This workshop is a first step into shell modeling within ANSYS Mechanical. We read a surface body part model into Mechanical and define the part thickness. We initially use spot welds to connect the model corners, set up the loads and boundary conditions and solve. Duplicating the model, we use edge to edge contact instead of spot welds to simulate full seam welds. Initially, the edge to edge contact does not work, and we use advanced contact options including the pinball radius and search direction in order to get the contact to work. We then compare the two weld methods’ deflection results.
DRD Workshop 12b - Stress Analysis of a 3-Part Assembly Model with Shell Finite Elements
We commence the workshop by importing surface bodies representing a 3-part assembly of a steel plate weldment. We define the part thicknesses. We explore the Contact Auto Detection options for defining contact between the three parts. We use the tolerance slider bar and the priority options to tweak automatic contact creation.
DRD Workshop 12c - Assembly Modeling with Solid Shell Elements and Virtual Topology
For instances where you have a model that is a good candidate for shell modeling, yet you don’t have the capability to create surface geometry (for example, in DesignModeler with Midsurfacing), you can use Solid Shell elements. This workshop shows the student how to create Solid Shell elements, which require sweepable geometry. To achieve sweepable geometry, the student is introduced to Virtual Topology; this technique allows the user to combine split faces or edges into a set of entities within Mechanical. A Sweep Method can then be applied to the geometry to create Solid Shell elements.
DRD Workshop A: Thermal-Stress Analysis of a Heat Exchanger
A first look at performing a thermal-stress analysis of a heat exchanger. The user is introduced to thermal loads, convection and temperature, and the model is solve. An energy balance is performed using the temperature reaction loads. Following this, the temperature profile of the heat exchanger is fed into a structural analysis through the Workbench project schematic and a simple structural analysis is performed.
DRD Workshop B: ANSYS Mechanical Integration with ANSYS MAPDL (or ANSYS Classic)
This workshop exposes the user to the integration of Mechanical with MAPDL, or ANSYS Classic. The students create named selections within Mechanical as well as command objects and then transfer the model into MAPDL. The student explores using MAPDL for object selections, defining loads and solving the model. This workshop is a first look at using MAPDL commands to augment an ANSYS Mechanical analysis.
DRD Workshop C: Rigid Parts and Joint Connections in a Front-End Loader
In this workshop the user assigns joints to the lift bucket assembly shown, assigns some parts as rigid and other flexible, and runs the bucket into a fixed obstacle to observe the resulting stresses, deflections, and joint loads.
DRD Workshop D: Modeling with Node Merge a Sandwich Composite Comprised of Honeycomb Core and Aluminum Faces
In this workshop the user is exposed to the Mesh Edit technique to merge nodes, simplify the model construction, and avoid any contact definition between the various components. The natural frequencies and static stresses in this honeycomb structure are then calculated.
DRD Workshop E: Modeling a Structural Weldment with Shell Elements and Mesh Connections
This workshop takes a shell assembly and uses mesh connections to merge nodes at the joints instead of using bonded contact to carry the load between the components.
DRD Workshop F: Fatigue Life Prediction for a Shaft with Axial and Shear Loading using the ANSYS Fatigue Module
This workshop calculates fatigue life of a cast part for fully reversed, zero based, and nonproportional loads. Also uses Solution Combination to calculate mean stress and alternating stress. A design change is made and the new fatigue life and mean and alternating stresses for the new design is calculated with the ANSYS Workbench Fatigue Module.
DRD Workshop G: Strain Life Fatigue Analysis of a Motorcycle Fender
In this workshop the user determines the minimum fatigue life of the fender bracket shown. This fatigue exercise is done by using strain-life fatigue options within the Fatigue Module and the default structural steel material in ANSYS Mechanical.
