Hey folks, a technical question for y'all. I'm designing the anti-sway bar assembly for my '66 Mustang track car. I've chosen my sway bars according to a 56% front dynamic load distribution, and have come up against the next problem: designing the parts of the assembly to each resist the loads placed on them. For instance, how much load will the end links, brackets, and a-arms have on them in the worst-case scenario?
I'm having a bit of a mental block here. In my mind, in a max-load situation (say, a 1.2g turn), I see the max load placed on the sway bar as the un-sprung weight of the inside wheel. This doesn't sit right, as the load is WAY too low. Can someone help me figure out a more appropriate solution path to determining the max load on the assembly? Obviously, a vertical load at the wheel or pick up points, or a twisting moment on the bar could all be converted to a load in another component - It doesn't matter how it's stated. Just help me out!
A few helpful details about my car
~3000 lb vehicle, 55% front weight dist
~75 lb front un-sprung weight per corner
~100 lb rear un-sprung weight per corner
3800 in*lbf / deg front roll resistance due to springs
3536 in*lbf / deg rear roll resistance due to springs
9604 in*lbf / deg front roll resistance due to roll bar
2950 in*lbf / deg rear roll resistance due to roll bar
Help!
Thanks, guys and gals!
