Subject: Re: Swaybars: Size matters? by gkmccready on 2008/11/10 15:57:36 Quote: I can't speak on why it's needed. My guess would be that springs alone could be made stiff enough to be equivalent to the bar, but the car would ride like shit everywhere else. I don't think wheelbase has much to do with it. Hm. I was wondering if it was the distance from the CG to the actual weight that could let the spring rates be lower if only controlling front<->rear weight transfer, and that's why we needed to add left<->right roll stiffness with swaybars on top of the springs. Or is it simply that we can generate more cornering force than braking or acceleration forces? Is that statement even true or can we generate the same forces? I am a little confused, somewhere over the years somebody told me that with a solid bar and a hollow bar of the same diameter the solid bar would be softer. I never understood that -- it sounds like you're saying that's not true? Also, if the formula says (OD-ID)^4 won't the material required to make an equally stiff hollow bar come to the same amount of material? |
