What is the Static Stability Factor? aka T/2H?
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...

Questions on the CCI Option
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...

Damage Analysis for High Speed Impacts?
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...

SMAC/HVOSM tire model analytical formulations
Q: I am doing a study of the tire force models used in various vehicle dynamic simulation programs. The McHenry write-up on Cornering Stiffness from your accident reconstruction seminar sketches out the form of the m-smac tire model but does not give details. For example, how are the lateral stiffne...

CRASH program sensitiviy for rotation < or > 360 degrees?
Q: I have been told both by the police that for their WinCRASH reconstruction they have my car rotating 360 degrees before stopping. It did not do that but they say if it did not it would produce a faster speed, not a slower one. My uneducated brain thinks that to spin a car would take more weight a...

Is 'car was 2 deg off zero' an accurate collision desc?
Q: Is it possible to accurately explain the who's, whats, where's and how fast an accident happened using any accident reconstruction technique,or is one better than the other.I am being told the car was 2 degrees off zero which indicates closeness to the center of the road.Is that true,or could it ...

Question on McHenry James Bond Spiral Jump Stunt
Q: I am wondering what is the accuracy of the statement about the stunt "With a 39.9 mph take-off speed, the weight of the Hornet being exactly 1460.6 kg (including passengers), and the distance between the klong ramps being exactly 15.86m apart, Bond perfectly executes the jump." A: The S...

What is the Lowest Speed for an injury?
Q: What is the lowest speed a vehicle could be traveling that would still be considered a high impact injury? A: Impact severity is generally based upon the impact speed change which is the time rate of change of the vehicle/occupant during a collision. There are many variables which go into the det...
