QUOTE(r_towle @ Jan 26 2007, 07:17 PM)  The whole chassis resonance thing was done, and a detailed article of the test on a 914 appeared in "up-fixin der porsche" (I forget which one) The test was done in a big lab in CA, and the results were a cage built to add strength the the 914. It would be great to see that article. I've already found some numbers for comparison. http://www.bmwworld.com/models/z4/suspension.htm QUOTE "The correlation between chassis rigidity and athletic handling has long since ceased to be a mystery," wrote Car and Driver in its April '02 issue. BMW knows this: With each new vehicle generation, BMW further advances vehicle dynamics by improving this "stable platform" of chassis rigidity. Thus BMW's structural engineers have developed a body/chassis structure with exceptional stiffness for a roadster. They achieved 21 Hertz - truly outstanding for a roadster, and close to the 25-26 Hz of today's BMW sedans. |
