    When To Use A Bearing Load

    Friday, January 25th, 2013

    The use of a bearing load is brought up frequently during training and technical support discussions. I want to elaborate on this topic with a simple example, illustrating when to use and when it is not necessary to use the bearing load.
    Let’s step back a minute and talk about what a bearing load is. According to the SolidWorks Help file:

     

    Bearing Loads


    Bearing loads develop between contacting cylindrical faces or edges of shells.
    In most cases, the contacting faces or edges have the same radius. The bearing forces generate a non-uniform pressure at the interface of contact. You can select between a sinusoidal variation and a parabolic variation in the appropriate half-space, as shown in the figure.

    Bearing Load Distribution

    In contrast, a uniform load does not vary in strength closer to the tangency of the tube. The load is constant across the applied face.
    Setup:


    We will examine two models and four scenarios in this exercise. The models will be both a solid and a hollow shaft. The shaft dimensions will be 14″ long with a 2″ diameter. Additionally, the hollow shaft will have a wall thickness of 0.125″.
    Both the Solid and Hollow tubes were loaded with a distributed and bearing load in order to compare and contrast the results. Both models were held fixed at either end. The load was applied to the entire length of the top half of the shaft in a vertical direction.

    Loading
    The Results:


    Between the distributed and bearing load on the Solid model, there is no difference in stress and displacement. On the hollow tube, the bearing load shows a drastic difference in the displacement compared to the uniform load. The bearing load shows the majority of the load is being focused on the center of the tube.
    Model Load Stress Displacement

    Model Load Stress Displacement
    Solid 2000lb Distributed 3943.6 psi 0.001066 in.
    Solid 2000lb Bearing 3943.4 psi 0.001065 in
    Hollow 2000lb Distributed 11,534.6 psi 0.003009 in.
    Hollow 2000lb Bearing 12,084.9 psi 0.003467 in.

    Significant digits are for illustration only.

    The stress is 4.5% higher in the ‘hollow shaft – bearing load’ combination as compared to the ‘hollow shaft – distributed load’ example.

    Summary:


    In summary, the bearing load should be utilized when dealing with a hollow or thin walled, cylindrical geometry. Utilizing solid geometry the load differences do not affect the results. The solid geometry distributes the load throughout the solid volume and is inherently stiffer. The hollow tube, missing its internal mass, shows a difference in the displacement of the applied load. The uniform load displaced evenly from tangent edge to tangent edge where as the bearing load concentrated in the center.

    A bearing load can be applied to solid and hollow cylindrical geometry however it is only necessary for hollow or thin geometry.

    Exclusive CSWE (Certified SolidWorks Expert) Event

    This is the very first year SolidWorks has upped the prerequisite certification from CSWP to CSWE.  Last year, there were about 900 CSWP’s at the event, and there’s only about 200 CSWE’s expected to attend this year.  Though this has some CSWP’s feeling a bit left out, it only means bigger door prizes and grand prizes for the rest of us.  :  )

    Almost our entire technical team will be going, and two very special customers will be joining us.  Craig Riedel and Jerry Kassil of Beckett Gas, Inc (in that order) were the very first (and only) non-VAR employees to earn this pinnacle certification in Ohio and Kentucky.  Congratulations!!!  Below is the list of certified CSWE’s in the two states as proof.

    I’m really looking forward to the event this year, and I hope to see you there.  In the meantime, you can stay tuned to my tweets of #SWW13.

    Submodeling in Simulation 2013

    Friday, January 18th, 2013

    Was it really last year that Vik wrote about Two Neat Additions  to Simulation in 2013?  How time flies!  For all its power, the addition of Submodeling studies for Simulation 2013 has seemingly gone unnoticed by our Simulation user base.

    In most cases, we are usually interested in the performance of a small portion of the model, maybe a part or two of the whole design.  In order to get to that area of interest, we need to analyze a load path through other components.  What submodeling does is allow us to generate analysis results on an entire assembly, then utilize those results on our area of interest in the mechanism.  This is done by using the displacements from the assembly and transferring those as a fixture (a prescribed displacement) on the components of interest.  Let’s show how this works in Simulation.

    Here is the Frame model we demonstrated Submodeling on during the SolidWorks 2013 Roll-Out sessions.  The boundary conditions have been applied to the entire model, but our real area of interest is the middle cross brace and associated components.

    We conduct the analysis on the entire frame, specifically looking for the displacements results of the assembly.  The displacements at the cut boundary between the entire frame and our important component(s) is what we are interested in to begin a submodeling study.

    To start the Submodeling study, right-click on the Simulation study name and select the option ‘Create Submodeling Study’.

    The next step is to select components – the ones we are most interested in – from the graphics window.  Simulation will take a few moments to generate the derived configuration and transfer the displacement results at the cut boundary into the submodel study.

    Now you can run an analysis with a very refined mesh on the important components of the design.  The real benefit of submodeling in Simulation, however, has to do with evaluating design changes.  If the cut boundary remains unchanged and the loading conditions stay the same, you can evaluate design changes to the submodel and verify the effectiveness of those changes without meshing and running the analysis on the entire assembly.

    Here we see that a slot has been cut through the main portion of the cross frame that would remove a lot of mass from the component.  We can recalculate the results of the submodel study with this design change and feel comfortable that our results are valid.

    So the next time you begin a study on a large assembly, resist the temptation to drag the mesh density slider all the way to fine.  Just generate results for the entire assembly with a coarse mesh, create a submodel study and then refine your mesh as you see fit.  Now go make your products better with SolidWorks Simulation!

    Workflow and Specification Flow

    Tuesday, January 15th, 2013

    A little more than a year ago, with DriveWorks 7, DriveWorks introduced Specification Flow. Many people rejoiced, many were confused. I had several people ask why they would need specification flow when they already had workflow through their PDM.

    At first glance, many Enterprise PDM users assume the two functionalities overlap…their interfaces look rather similar and they both have similar sounding names, but actually they [can] have completely different functions because they fit in different areas of your company’s order timeline.

    DriveWorks’ specification flow is oftentimes the flow of a potential order…before any files are even generated.

    SpecificationFlow

    The specifications of the order can be stored within DriveWorks, you can make changes, generate approval drawings, even have people approve the acceptance of an order without any files having to be generated.

    Once you and the customer agree it is time to start, DriveWorks can create the files (CAD, BOMs, acceptance letters, spare parts lists, ERP information, etc.) place them into the PDM system where they can then have their own workflow independent of the DriveWorks system.

    Learn more?

    You may have a quoting process which involves generating a general-assembly drawing – all before releasing to manufacture and before the full manufacturing information is generated.
    You may have additional requirements during the specification process such as copying a document to another machine which otherwise would involve complicated macros.
    You may simply want to change the text that is displayed on the “Finish” button to something like “Quote”
    You may want to set rules that determine that a Sales Manager can see all specifications generated by your distributors, but only let each distributor see their own specifications.

    Viewing same part from different views

    Monday, January 7th, 2013

    Ever wanted to look at the same part from different views ?
    Well there are two nice ways to accomplish this in SolidWorks…

    One way is to use the WINDOW–VIEWPORT–TWO VIEW or FOUR VIEW commands.
    You will then be able to rotate one of the views to look at the Front of your part/assy and another one to look at the back, etc.

    The second way is to use the WINDOW–NEW WINDOW command.
    This will “clone” the window you have active but you don’t really see it.
    So then you do a WINDOW–TILE VERTICALLY or TILE HORIZONTALLY to see the two windows looking at the same part/assy.
    This method is also great for looking at two different sheets of a DRAWING at the same time !   Where as the first method won’t allow this in a Drawing.
