    Spiral bevel gear analysis

    "The gear is rigid,and the pinion is free to move on Theta." What is applying the torque load? Can you put your model?

    Force settings Make No difference

    SolidWorks does a linear scaling of the deformed shape so that the user will be able to visually see it. If you want to compare the displacements between different materials and loads, you need to look at a displacement fringe plot and see what the maximum displacement value is on the legend...

    ProE Mechanica, Buckling Perpendicular to the Load?!

    Can you upload the model itself? Have you looked the the 2nd, 3rd, and 4th mode of buckling? Are you meshing the geometry with solid elements? If so, be aware that the rotational DOFs on your constraint are NOT locked; solid elements only have three DOF per node (all translation). "I had...

    what kind simulation or tool shouhld i use for this problem

    Other than hand calculations, you could use SolidWorks Motion.

    Simulation of cutters

    I can't DL your model at work, but I do have a few pointers/questions. How did you model the pin connection? Did you use CAD geometry? If you did, then I suggest you remove the pin CAD and add in a pin connection within SolidWorks simulation (make sure to allow on axis rotation). Does a fixed...

    Simulating A Tapered Pin Constraint

    To what level of accuracy do you need to model a tapped pin connect? Do you just need a connection that allows on axis rotation? Does it need to provide mechanical stiffness in only one direction? What level of accuracy do you need from a results standpoint? Are you wanting accurate stresses at...

    Assembly Problems Non-Linear Analysis

    To start, Simulate/Mechanica has limited function for nonlinear analyses compared to linear analyses. For example, Simulate/Mechanica does not support shell, beam, and advanced spring elements in nonlinear analyses. A "Perimeter Weld" involves the creation of shell elements, so if you try to run...

    stresses in a steel band clamp

    Are you asking how you'd calculate this in ANSYS, or calculate it by hand?

    Explicit Analysis in ANSYS

    LS-Dyna is a 3D party code; do you have the license for it?

    I want to simulate 3d-printing model with varying printing direction. any suggestion?

    I'm a little confused as to what you're wanting to do. Do you want to know the best way to model an object created on a 3d printer? Anyways, from my limited understanding of the material nature of 3d printers, I would assume a composite layer layup approach would be the best way.

    Transient Shock Analysis in Creo Simulate vs Ansys

    Something just occurred to me that I should have caught at the start. You said you were doing a shock analysis, so I assumed you were using the Dynamic Shock in Creo. However, you said you were adjusting the damping ratio value in Creo, which is something you can't do in a Dynamic Shock (since a...

    "one or more contact regions may not be in initial contact"

    What do your deformation results look like?

    Uncertainty in transient simulations

    Kevin, can you provide more information was to why you can't refine your mesh further? Can you also provide some more information about what type of simulation you're doing? Are you trying to do a drop/impact test? Is the event highly non-linear, requiring non-linear dynamics? Maybe I'm not...

    Shock Response Function in Ansys

    Hopefully I'll be able to clear up some misconceptions. The dynamic shock method come from the days when hand calculations were used to estimate the response of a structure to a transient event (like a blast, impact, seismic event, etc). This type of analysis uses a Response Spectrum Curve...

    Patran: Replacing parts of FEM with resulting forces & moments

    If I understand what you want to do correctly, then this sounds like an ideal candidate for sub-modeling. With sub-modeling, you map the nodal displacement field results as enforced nodal displacements along the cut-faces.

    Transient Shock Analysis in Creo Simulate vs Ansys

    Regarding your question, "how do you know which damping coefficient provides you with the most accurate answer?", what do you mean by, "accurate answer"? Are you asking what damping ratio you should use on a (for example) welded steel structure?

    Transient Shock Analysis in Creo Simulate vs Ansys

    That should be enough modes. Regarding the mode combination method you used, look in the analysis definition under the, "Response Spectrum" tab. Wait, you were told that you can't use modal superposition because you're using a displacement constraint? Do you mean you're applying a prescribed...

    The end of Creo Simulate ?

    "In an effort to optimize the product development of Creo Simulate we looked to create a center of excellence for Simulation development. The chosen location was India and thus we shut down the San Jose office." So, to put to plainly, the US development team was outsourced to India to reduce...

    The end of Creo Simulate ?

    Mark, On another forums site (I think MCADCentral) someone who stated that they were the, "chairman of the PTC/User Technical Committee" said that the entire San Jose team was dissolved; is this true?

    Transient Shock Analysis in Creo Simulate vs Ansys

    What level of convergence did you get on the modal analysis for both Simulate and ANSYS? How many modes did you ask the solver to calculate for both? What results combination method did you use for Creo and for ANSYS? Creo has Absolute Sum and Square Root Sum of the Squares, where as ANSYS has...
