Wow, that ran a bit.......

Thanks for your well made comments Julian. I will agree that my rig was rough and ready, but I like to think my results at least give me a indication of how stiff my chassis is.

Did you do any tests with a drivetrain in? As stated by various people above, a real world test would be ideal, but it would be very inconvienent to build up (or model) a whole car when you are trying to do comparative or iterative tests on a chassis design.

WRT to the CAV test, I though that the fact that the load they applied was such that they only recorded just over a tenth of a degree of actual twist will make them very suseptable to any errorr. They would have only recorded about half a mm on their dial gauges (up one side, down the other, at the 300mm from centre span distance they used.

Cheers
