    Apr 01, 2015· The abrasion wear is shown in the left and the impact damage is shown on the right. The impact damage is concentrated on the central upper section of the inclined moving jaw where the feed stream lands. The distributions are quite uneven over short periods of operation as a result of the specific collisions and interactions that have occurred.

    How to calculate impact force? G-force in car crashes. Impact force formulas we used above describe an ideal collision between two objects. In the real situation of a car crash, the profile of force during the accident can be more extensive e.g., you should take into account that car collapses and that a human is not a point mass but a complex body.

  • Crash simulation Wikipedia

    A crash simulation is a virtual recreation of a destructive crash test of a car or a highway guard rail system using a computer simulation in order to examine the level of safety of the car and its occupants. Crash simulations are used by automakers during computer-aided engineering (CAE) analysis for crashworthiness in the computer-aided design (CAD) process of modelling new cars.
