Pdof in vehicle collisions
SpletCollisions between two vehicles: basic collisions and impact types. NOTECollision type (3.3.1.1)is used to describe a collision with respect to all vehicles, road users, and … Spletrelative to the vehicle structure. This requires the Principal Direction of Force (PDOF) be determined prior to the simulation. CRASH3 assumes the impact center is the crush centroid and attempts to estimate the angle from the deformation severity. However, it may often be quite difficult to estimate PDOF from the crush pattern because of

SpletIn full engagement collisions, PDOF is relatively constant through the crash (Rose, Fenton, & Ziernicki, 2004). However, real-world collisions often are not full engagement and may involve sliding (e.g. against a guardrail or side of another vehicle). Although technically an improper use of PDOF, PDOF may be a reasonable indicator of impact SpletObjective: To measure the combined contribution of change in velocity (Deltav), principal direction of force (PDOF), and restraint use on mortality after vehicular trauma.
