Collision simulation software

  • 04-Feb-2009 06:56 EST

Version 2 of Engineering Dynamics’ DyMESH (Dynamic MEchanical SHell) software provides 3-D simulation of collisions between multiple vehicles as well as vehicles interacting with the environment such as embankments and bridge abutments. Combining methods from finite-element technology and traditional stress-strain relationships, DyMESH produces a fast-executing, yet robust, collision model. The result is complex simulations that can run in seconds or minutes rather than hours. The detailed results from a DyMESH simulation include collision forces and moments and body deformation vs. time. DyMESH is suitable for simulating all types of vehicle-to-vehicle collisions, vehicle-to-barrier collisions, and vehicle vs. environment collisions. It is also useful for simulating over/under ride, rollover, or any crash where 3-D collision dynamics are important and need to be simulated.
