Re: Question on CRASH3, Effective Mass, Closing Speed

Q : In Gordon Bigg's WinSlam , the closing speed is defined along the Principal Direction of Force (PDOF), which acts at the centroid of damage. Also in Winslam , the closing velocity is defined as GB_CVeqn.png The CRASH3 delta-V equations give the delta-V at the Center of Mass (COM). Using the del...

Question on CRASH3, Effective Mass, Closing Speed

Q : We are trying to come up with an adjustment for Airbag Control Modules (ACMs) that are not located at Center of Mass (COM or CG). Consider the following diagram: DeltaV_at_Location.jpg Our testing shows that the vehicle depicted will rotate about the right front tire. That means that an Electro...

What is the Barrier Impact Angle Equation?

Q: What is the Barrier Impact Angle Equation? The Barrier impact angle equation is used to determine the approximate maximum angle of a vehicle departure from the road for a given lateral distance. The ability of a vehicle to change its direction of motion is dependent upon its forward speed, the u...
