JFryer Posted February 23, 2003 Share Posted February 23, 2003 In my search for info on antiroll bars I broke out the text books (Trig) and did some calculations using formulas from Don Alexander's book PERFORMANCE HANDLING. These rates are in pounds per inch of deflection, and are based on stock antiroll bar shapes both front and rear. (if sombody would post the dimensions for the rear type that mounts to the uprights I will calculate it and post.) Front 16mm 75lb per inch 18mm 120lb per inch 20mm 183lb per inch 21mm 223lb per inch 22mm 268lb per inch 23mm 321lb per inch 1" 447lb per inch 1 1/8 717lb per inch REAR 20mm 86lb per inch 21mm 105lb per inch 7/8" 139lb per inch 1" 211lb per inch Hope somebody else finds this usefull Quote Link to comment Share on other sites More sharing options...
80LS1T Posted February 23, 2003 Share Posted February 23, 2003 Are you talking about sway bars? Guy Quote Link to comment Share on other sites More sharing options...
Top Fuel ZX Posted February 23, 2003 Share Posted February 23, 2003 antiroll bars = sway bars Sean Quote Link to comment Share on other sites More sharing options...
johnc Posted February 23, 2003 Share Posted February 23, 2003 Is your calculation of the deflection number: 1. The total deflection of both arms measured at the link mount holes 2. The total deflection of both arms measured at some other standard point on the arms. 3. The amount of twist in the bar itself? Quote Link to comment Share on other sites More sharing options...

Hopefully it would be 1.) above' date=' as that would be the most meaningful answer. I guess [b']2.)[/b] would be okay if you knew where the reference point was. 3.) would need to be in lb-ft/degree to be meaningful. Quote Link to comment Share on other sites More sharing options...

The amount of twist in the bar itself? # 1 is correct. This is the formula I used if any one is interested. 315294.1 X R4 X O A X L R4= effective radius of the bar to the 4th power 0 = angle of deflection in degrees A = effective arm length L = effective bar length Quote Link to comment Share on other sites More sharing options...
johnc Posted February 24, 2003 Share Posted February 24, 2003 And A is the sum of the length of both arms, correct? Quote Link to comment Share on other sites More sharing options...
