Strut bar fabrication gone wrong, Need advice Options

[UVZ164]

Have you used Abaqus before?

Is that the simulation environment inside Solidworks? if so only once, I mainly use ANSYS

interesting, i would run it again with a straight bar, I think the bend would cause more deflection than a shorter straight bar.
Just a guess, I have no software to test this, but I have been making parts on cnc mills for 20 years, so understanding rigidity is
something I have tried a time or 2. afaik the bend seen in some bars is a clearance thing for top mount IC, I doubt it is adding any rigidity.
Bicycle frames and forks are a good example of rigidity in action, the materials used have a lot to do with it also. Chrome moly should be
a great strut bar material imo.

A straight bar will withstand ALOT more force than a bent bar of any sort. This is due to a buckling situation that we encounter as both sides are in compression and fixed. Doing the calculation for the flat bar I used I found that it will take a compression force of 8909.29 N at each end to cause the bar to begin to bend.

The other reason that a bend is necessary is due to things getting in the way like, air intake piping, bonnet supports, throttle cable. So really it becomes impractical unfortunately.

flat should be fine...



i would add the little triangles at the end of mine

If that's the J-speed one, that's what modeled mine off, I just couldn't be bothered to make the triangles haha


If my thesis supervisor is feeling nice after Christmas i might even try to persuade him to let me hook some strain gauges up to it and then we can get a pretty good idea of what kind of forces are being put on the bar.

J speed it is!!

A straight bar can't work as it hits a few things along the way and the bends also provide some extra rigidity

regardless it is going to be much beefier than stock

Make sure to throw the stock one on there for a test, see just how flexible its tubular design is in comparison to something made out of flat metal stock.
