PC Crash Features

The ability to import 2D or 3D scenes or create them within.

 

2D or 3D collision model based on conservation of linear and angular momentum, restitution and contact friction (for sliding impacts)

Collision Optimizer algorithms that reconstruct collisions using scene data and/or crush energy (see SAE 980373)

Collision and trajectory analysis of multibody pedestrians, occupants, two wheeled vehicles and other objects**
Analysis of rollovers and vaults Variable suspension and tire parameters
Steering with driver input sequences, defined paths, or independently on wheels bent by damage ABS and normal braking (with front-rear distribution valve for 3D vehicles), individual wheel braking

Simultaneous simulation of up to 32 vehicles and objects**

Built in 3D animation with fixed or moving camera**
Optional interface to MADYMO ® **PC Crash 3D
New Features of PC Crash 7.3

Impact Models - Ellipsoidal and Mesh Models

The force-based ellipsoidal model is useful for low-speed or sustained contact collisions and the more complex force-based mesh model can be used where the crash pulse time is an important factor or where residual deformation over a number of impacts occurs.

Either of the two force-based models can be used for ground contact in a rollover.

Trailer Separation Model

Simulate and perform impact calculations for truck and trailer combinations using one or more trailers. The multibody system allows you to take movable loads into account.

Model trailer seperation by either specifying a hitch failure for or a specific distance/time; trailers equipped with steering systems based on articulation angles can also be modeled.

Optional Interface to MADYMO®

The optional MADYMO® module allows vehicle occupant motion and loading to be studied.

Different types of seat belts can be specified, including a seat belt tensioner when a lap and torso belt is used. Two different airbags (driver's and right front) can be specified.

The results of a MADYMO ® simulation can be viewed as a 3D animation (left) or in the form of diagrams. Diagrams of velocities, loads, etc. on each multi-body component are available.

FCE 3D Vehicle Shapes

Thousands of freely available FCE 3D shapes, created for popular computer games, can now be imported in addition to the current DXF shapes. DXF shapes can change shape at impact, either automatically based on vehicle overlap at maximum engagement or with more complex changes defined by the user. The 3D DXF and FCE shapes can also be used for multibody pedestrian interaction, or to define the mesh impact model shapes.

Other Features:
  • Collision Optimizer Monte Carlo (random) algorithm, providing information on result stability and accuracy
  • A soft soil model
  • Kinematic calculation of post-impact velocities, based on up to six post-impact positions and braking levels for each vehicle
  • Crash backwards calculation, using post-impact velocities and either momentum or crush energy to determine pre-impact speeds
  • Automatic kinetic calculation of accident avoidance, with either gradual decrease of speed or increase of raking level until impact is avoided
  • Direct-X 3D graphics for improved rendering
