Title: Swept Path Analysis
Post by: Rick Brice on September 23, 2011, 04:31:19 PM

I'm looking to study swept path analysis. I was wondering if someone could direct me to techinical papers and text books that cover the subject.

Thanks

Hi!

Here are some links that might be of interest.

Thanks for the references. I've been able to find a lot of information.

Do you know of any reference material for modeling the turning movement of vehicles with independent rear steering dolly and vehicles with independing rear articulated trucks. These types of configurations would be used to haul long heavy loads like concrete beams.

Thanks

Hi!

I haven’t seen any documents on how to calculate rear steering. However I’ve been testing a simple approach on the rear end of a trailer.
The simplest is to let the rear axle follow the turning path and that was the approach I tested. This assumption could be wrong but it shouldn’t be impossible for the rear axle to follow same path as the front axle of the truck. There might be a more effective path for the rear axle especially if a human steers it

It is not included in any of my turning software because it’s was just a test.
