Simulation Downloads (Animations)
The math models in BikeSim, CarSim, and TruckSim produce files with time histories of hundreds of variables. This page has several options for viewing results for a few of the example runs that are included with the software.
- For a rapid glance, click on the thumbnail picture for a larger static view taken from the animator.
- The animator shows vehicle motions using high quality animation. You can view the animations from this page in full resolution for your monitor, with full control over camera point of view, zoom, speed, and other options. Install the SurfAnim player (once) to view all of these animations.
- Some of the animations also have sound sources with 3D locations. You should notice changes as you zoom in and out and move the camera relative to a vehicle.
- The animator can export multimedia files, such as Windows Media player (.wmv files). These are also available for download for the examples on this page. They are less detailed, less interactive, and have no sound. However if your firewall prevents downloading SurfAnim player, you can still see the simulated vehicle motions.
- The plotter shows variables as functions of time or other variables. Overlays are made with multiple runs, and labeling and scaling are automatic.

The SurfAnim Player ProgramThis program plays UAF files and gives you full control over the camera and view, including position, zoom, slow motion, multiple images, audio, etc. The installer also loads the OpenAL library necessary to hear the audio components in some of the simulation results. If you do not have Administrator permission, then the Audio library will not be installed. |

Active Speed Control with Sensor BeamTwo vehicles interact in a Simulink model. The trailing vehicle has a radar sensor that controls speed when another vehicle is detected. The beam is shown in the animator as a green translucent shape when no vehicle is detected; the beam color changes to red when detection occurs. This run is an example provided in CarSim 7.1. It is silent. Two animations can be viewed: one from an external camera, and one from the point of view of the second vehicle, including a heads-up display (HUD). |

Reverse Spin Maneuver with Skid MarksAn example of using Event conditions to define a complicated driver control. When specified conditions occur, new datasets are loaded to change control definitions. For this example, the driver will: Go in reverse to -45 km/h, then steer until yaw angle reaches 45-deg; then hit the brakes until the speed drops, then go full speed ahead while steering in closed-loop to regain control. The Animator EXE has audio. |

Simulating and Animating Traffic"Fake" vehicles are defined with runtime VehicleSim command. Their positions can be used in external models (e.g., Simulink), and they can be animated. Four vehicles are repositioned automatically after passing the CarSim vehicle to reappear, over and over. The "live" vehicle (the red sports car) has audio. Zoom in to hear the engine and gear shifting. |

Understeer in TruckSim (with Audio)The animation shows a basic understeer test, with the resulting plots. The animation include the sounds of the bus engine and shifting. Animator UAF (6 MB) | Movie WMV (3 MB) | Plots |

Double lane change in CarSimThe animation shows a basic double-lane change maneuver. The animator uses multiple images (ghosts) and tire vectors. This run is silent. Animator UAF (5 MB) | Movie WMV (0.7 MB) | Plots |

Rollover Test with OutriggersA comparison showing a basic rollover test for a vehicle with and without outriggers. Outrigger forces are defined in CarSim using runtime VehicleSim commands to define vertical forces that occur when the outriggers contact the ground. This run is silent.

ABS Braking Test on Split-Mu SurfaceCompare two trucks in a basic braking test on a split-mu surface. One has ABS, the other doesn't. The animator overlays the two runs. The plots shows the ABS cycling during the test. Note: the sound effects were not adjusted for low-friction, so it's a little noisy. |

Racing Lap with Sound and HUDThis animation includes audio linked to engine RPM, wind speed, tire slip, etc. Heads-Up Display (HUD) shows some simulated instruments. Animator UAF (7 MB) | Movie WMV (1.5 MB) |
