CartieSim Gets Trackmaster Import

CartieSim - Click to enlarge A new version of SCA CartieSim, the SCA's cartie speed estimation software, has just been released. There are numerous tweaks and bug fixes in it, but the main changes are;

  1. New "Quick Edit" tool which allows you to quickly see the effect of changing cartie weight, rolling resistance, CoG height etc.
  2. Direct import of excel files created by Trackmaster. If you've logged an actual race as a single session, you'll see each run overlayed on the speed profile.
  3. Estimation of braking points and deceleration under braking for tight corners and chicanes.
The latest version can be downloaded from here.

SCA Develops Cartie Simulation Software

The SCA's back room boffins and their clever little coding elves have been busy doing some fiendishly clever things with computers of late, and they are nearly ready to launch a full blown cartie simulator on the unsuspecting gravity racing world.

SCA CartieSim is a application that can predict the speeds of a cartie at any point on a course from some simple data describing the cartie and the coordinates of the course. The course can be loaded from a GPS data file or, if you don't have access to that, then a simple route from Google Maps or Google Earth can be loaded instead.

Taking into consideration such variables as overall mass, drag factor and rolling resistanc along with the gradient and turn radius of the course, the application plots a profile of speed against distance and can even identify sections of the course where you may need to use your brakes!

Key features:

  • Course data loaded from GPS file, CSV file or online from Google Maps and satellite altitude database
  • Simple "Course Wizard" guides you through loading a new course
  • Calculates speed profile, time and maximum speed
  • Calculates course data such as total length, average gradient, maximum gradient
  • "Critical Velocity" calculation predicts sections where braking may be required
  • Models dead, push and ramp starts
  • Models different cartie configurations for comparison
  • Calculates stopping distance after finish line
The program is currently in its final testing phase, and the first production version should be available in the next few weeks.
