The following are some references on Heavy Truck Crash Tests. This is no way comprehensive. Please add to the list. Just a few references I found within arms reach. Truck Crash Testing, E. Franchini, SAE 700411 Truck Tests on Texas Concrete Median Barrirer, T.J. Hirsch, PB 220 853 Heavy Truck Pilot ...

There have been some experimental tests run on the effects of vehicles in proximity to trucks. A quick look brings the following reference: Aerodynamics of Passenger Vehicles in Close Proximity to Trucks and Buses Robert Heffley, Systems Technology (STI), SAE paper 730235 The full report was perform...

New: Use this link to go to the latest post on this thread To approximate the drag factor for a rotating vehicle, we caution against attempting to use any arbitrary % drag factors like: "50% to 80% of the standard drag factor" or "70-75% of the full drag". In our paper " CR...

The conventional form of vehicle damage analysis in the case of a central collision with a fixed, rigid object is based on the assumption of a full-term collision, during which the vehicle velocity is reduced to zero (e.g., figure 1). full term collision.jpg Figure 1 Full-Term Collision For the case...

A simplistic viewpoint is frequently encountered in which the so-called " static stability factor ", or T/2H , is cited as the ultimate measure of the rollover resistance of a given vehicle design configuration. The static stability factor is, of course, derived on the basis of a rigid bod...

For convenience here's a quick link to the latest post in this topic Questions about the CCI option: Question #1? I am reviewing a SMAC analysis which was run in McHenry and was wondering what the CCIX and CCIY variables represent? I am assuming it has something to do with the CG location but am no...

Q: Is anyone aware of papers discussing crash tests beyond the 35 mph NCAP testing? A: It has been suggested since the 80's that the damage analysis model of CRASH and CRASH clones should consider some possible modification for higher speed impacts. A good starting point for that discussion is Stro...
