Should one consider nuts & bolts of an assembly in meshing?

I'm working on a project on stress analysis of a typical truck chassis frame.

I need to mesh the chassis which contains 400 components, mostly nuts, bolts & washers.

Can I eliminate all the nuts, bolts & washers for simplified meshing?

Will it have an effect on the result?

Kindly help as I'm finding it difficult to mesh 400 components. Thank you (:

    Hi Adbul,

     

    you can eliminate and instead you can use ID elements to transfer load from one part to the other in the assembly.

     

    You may consider using beam or rod elements along the centerline of the bolt to join the parts.

    You can also use bolt connectors,

     

    see HyperWorks Desktop Applications > HyperMesh > User's Guide > HyperMesh Panels > HyperMesh Panels Listed Alphabetically > Connectors Module > bolt panel

    It sounds good. You can also use hex bolts. This information is also useful for others. I appreciate you for this. Good luck and keep it up.
