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 ® |

| 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
