Bicycle Frame with Beam Elements ANSYS Workbench

You can get a copy of the book here: www.amazon.com...
This video is a tutorial on how to perform an analysis of a bicycle frame in ANSYS workbench using beam elements. The tutorial is based on Case Study B from pages 355 to 363 of the book "Practical Stress Analysis with Finite Elements" by Dr. Bryan J. Mac Donald. In this tutorial we show how to build the model by defining construction points in 3D space and then using these points to generate line bodies. We then define different cross sections and assign these cross sections to the various line bodies. We also show how to correctly join and merge line bodies that have different cross sections into a single part so that the analysis will solve correctly later on. This tutorial also covers how to define your own material in ANSYS Workbench and how to correctly mesh line bodies for use with beam elements. We detail how to apply fixed constraints, regions constrained in certain directions only and how to apply forces in particular directions. Finally, we show how to get results from beam elements using the "Beam Tool" in workbench and how to display these results to understand how the model is behaving.

thanks man helped alot.

[@hong8515]

your god of fem thanks!!!

[@musayildirim9389]

thanks

[@fiqaz117]

that was a very good video. However i cannot excess the von mises equivalent solution for this matter. Why? and how to get von mises solution?

[@joeladrianmunozesparza205]

it was a good video. thanks

Glad you liked it!

what do you do if tou want to make a knee given the effective length of the knee (pipe)

[@gauthamd3895]

I habe done this analysis can i use this as my mini project?

[@sourabhjain1033]

Sir why did you remove your videos of ANSYS APDL explaining practical stress analysis with finite elements...where can I find those videos?

[@LearnFiniteElementAnalysis]

Hi, do you mean these ones: ruclips.net/user/GlasnevinPublishingvideos
They are a bit out of date and I plan to update them and post them to this channel.

[@sourabhjain1033]

@@LearnFiniteElementAnalysis yes those were the ones....thank you 😊😊

What should I do if I want to mesh the cross section as 2D mesh instead of 1D mesh?

[@LearnFiniteElementAnalysis]

Hi, I am not sure what you mean here. The bicycle problem is 3D so you could use 3D solid elements instead of beam elements if you wanted but I am not sure how or why you would use 2D elements to accurately model this problem

Why did you fixed the rotation too on the left vertex??

[@LearnFiniteElementAnalysis]

Hi, that was an error actually. Thanks for pointing it out. That is the reason that the results are slightly different from the results in the example given in the book. The left vertex should be constrained for all displacements but not rotation.

[@sherohanwithana9515]

So how do you correct this?

[@ABOSULTAN7TV]

is therea way I can get the safety factor ?

[@LearnFiniteElementAnalysis]

Hi, it is not directly possible to get the safety factor with beam elements, however, you can get it by defining a "user defined result". If you highlight the "solution" in the model tree, you will see that "worksheet" becomes available in the top right hand corner of the main window. Click on this and select (for example) MAX_BENDING. Right click on this and select "Create user defined result" - this will create a new result item in the model tree. To change this into a safety factor, click on it and then change the expression (which should currently be BEAMMAX_BENDING) to "BEAMMAX_BENDING/300e6" if 300 MPa was your yield stress - this will give you your safety factor. Hope this helps!

gettin a question mark on model in geometry...parts
