Impact, Drop and Crash Testing and Analysis Digital

Impact Analysis. It is useful to consider vehicle impact speeds to describe the different physics involved and that we wish to simulate. Consider a minor bump, such as overrunning a parking spot and hitting a lamppost. At around 5 mph, the resultant damage is not excessive. The hood may permanently buckle, and the front grille and bumper become

How to Calculate Speed by Crush | Sciencing

First, multiply the crush depth by the “crush factor.” This is a value based on statistical analysis of 1,000 accidents. It is available as a table (see References). Multiply this figure by 30. Find the square root of the total figure and this will give the speed of the vehicle at the point of impact.
