January 2004
1. Exhibit at the Autosport Engineering Trade Show in Birmingham, England
2. Work on Live Axle load calculations
3. Debrief3 and WinGeo3/Premier can read MATLAB Version 5 files as produced by PI Toolbox.
4. Add Analysis of Force Computations
5. Add Rigid Body analysis
February 2004
1. Begin work on LoadCheck matrix analysis of loads and suspension travel.
March 2004
1. WinGeo3 gets LoadCheck interface capability.
April 2004
1. Correct problems in the Setup and Undo commands.
2. Improve the Editing fields by adding total track and track-at-hub height.
3. Design gets Fit A-arm as well as Extend A-arm. Fit moves the inner pickup points laterally rather than extending them along the existing axis.
4. Redo Fixture by adding tire contact patch fore-aft information rather than requiring it to be at X=0.0. This simplifies the Fixture command.
5. Track can be measured at ground level or hub height.
6. Analysis: Origin released to public
7. Analysis: Angles released to public
8. Reports: Compare Results released to public.
9. Reports: Compare Points released to public.
May 2004
1. Attend SAE Vehicle Dynamics Academy planning session at BeaveRun race track near Warrendale, PA.
2. Attend Formula SAE competition in Auburn Hills, Michigan.
3. Save Map Display option.
June 2004
1. Work on monoshock derivatives.
July 2004
1. Panhard rod can be mounted in either direction.
2. Fixture displays tire diameter, radius and rollout.
3. Improve MacPherson Strut calculations.
August 2004
1. Display Steer in inches in the tables.
2. Add a Quick Table feature
3. Add MacPherson Strut with steering tierod attached to lower A-arm rather than chassis.
September 2004
1. Attend SCCA Runoffs at Mid-Ohio.
2. MacPherson Strut multi-link model added.
3. Work on steering rack graphics for rear suspensions.
4. Correct bug in the upright graphics when the fixture is used.
October 2004
1. Add Axis-of-Rotation analysis based on Enrico Nino Manes SAE paper.
2. Correct editing bugs related to tire diameter and tire contact point.
November 2004 - Release version 3.06
1. Release WinGeo3 version 3.06 with front and rear suspensions
2. Attend SAE Motorsports Engineering Conference in Dearborm, Michigan.
3. Present SAE paper “Driving the Traction Circle.”
4. Add View: Data panels to show iterative run data.
5. Add Trailing-Arm suspension (production BMW rear suspension) which rotates from one point, unlike a Trailing-Link which hinges about an axis. A Trailing-Link suspension has no additional links. A Trailing-Arm must have two additional links.
6. Develop the Swaybar calculation to make it consistent with load calculations. Positive values of roll (to the right as in a left turn) produce positive values of swaybar twist.
December 2004
1. Attend PRI Trade Show in Indianapolis, Indiana.
