I'm working on a project that requires me to design an overload control centre where overloaded trucks are allowed to redistribute or shed some of it's cargo in order to continue to travel on the highway.
As we are pressed for space I would like to make the design as economical as possible and maybe force the vehicles in a certain flow direction in order to ensure the longevity of the driving surface. But before I can do this I need to understand what kind of maneuvers are possible for the vehicles.
I am aware of sources that that has done that, e.g. AASHTO. There are also various plugins that exist for different CAD applications, some of which are free as well.
With this myriad of information, I still cannot find any information on how to determine this myself. It is trivial to do this for a car, but the moment the vehicle is articulated my attempts don't match what the sources tell me.
Can someone please explain to me how to determine the turning profile of any vehicle, given that I have the necessary information? My main concern is: How does the trailer react when a force is applied that is not perpendicular to its axle?
I know that I need certain information such as:
- The maximum angle that the front wheels can turn,
- The distances of the axles from each other
- Where the trailer pivot is in relation to the truck and trailer, etc.
