WinGeo3 Suspension Geometry

5.01 for Windows 95/98, 2000, NT, XP and Vista

New version 5.01 released November, 2008

WinGeo3 4.00 Suspension Geometry – A complete three-dimensional suspension kinematic program. Provides analysis of Double A-Arm, MacPherson Strut, Five-Link independent, and assorted solid rear-axle suspensions. The DOS Freebody suspension geometry program was the standard of the industry since it’s introduction in 1985. WinGeo3 is a Windows version incorporating all the graphic capabilities of the latest operating system and faster computers. WinGeo3 can compare two or more suspensions as the user manipulates the chassis in ride height, body roll and steering input. The user can also specify suspension travel and/or steer result and calculate the inputs providing that result.

The Advanced version adds Design capability that permits the user to create a suspension with the feature he desires. The Build and Fixture features allow the user to manipulate existing parts to create a suspension with desired characteristics. It also adds additional report preparation tools. The price for the Advanced version is $495. This is the least expensive version currently available.

The Expert version adds the Parts menu. This allows you to enter the dimensions of the hub/upright and assemble a suspension just as you do in the shop.

The Premier / Data version incorporates tire squash as a result of computer load and also load track data and compute the suspension parameters for any point on the track. The program can also analyze front and rear suspensions at the same time. The price for the Premier / Data version is $1,895.

Gear Ratio

3.04 for Windows 95/98, 2000, NT and XP

WinGears Gear Ratios – The complete gearing program for road racing and oval tracks. This program performs all of the standard gearing calculations but also utilizes an inventory of available gears to quickly show alternatives. This program has been developed at race tracks across the country to perform the functions race teams actually need. The Regular version is $195. 

 The Advanced version performs straight-line acceleration simulations. Provide gearing information with an engine torque curve and vehicle parameters and calculate vehicle acceleration. The Advanced version is $395.

Driving Simulator

3.01 for Windows 95/98, 2000. NT and XP

Driving Simulator -    The Wm. C. Mitchell Software Race Driving Simulator teaches competitors how to choose a proper racing line based on the traction circle and apply variations to solve tactical problems. A car specified by the user runs the various lines generated, computing split times for instant comparison.

Learn when to apex early or late and when to use a diamond line.
Learn the trade off between mid-turn speed and getting to the throttle.
When do you sacrifice speed to get to the throttle sooner?
When do you maximize speed at the expense of early throttle?

Learn how the car's capabilities - power, cornering, braking - relate to racing line choice. Learn how to alter your line to pass an equal car.
Learn how to set up a repass.

Learn when exit speed is over-rated. The Simulator may surprise you and debunk a few myths.

Warning: The Race Driving Simulator is a teaching tool for the serious racer, not a hand-eye coordination game.

Debrief3

3.04 for Windows 95/98, 2000, NT and XP

The Debrief3 data acquisition analysis program is a professional tool developed over a decade of use by the author. The Windows 95/98 program provides the analytical power required to make sense of the data collected on a race car. Debrief3 can directly access data from Corsa Instruments, Edge and Competition Data Systems and also access MATLAB files created by other data acquisition systems.

Debrief3 can load entire runs of data or individual laps. Five laps can be compared. The user has a great deal of control over the data display. The Debrief3 program is $495.

  Engine and Chassis Calculator 

3.02 for Windows 95/98, 2000, NT and XP

Frankly, you could do all of these computations on a calculator.  The advantage of the program is that they remember all of the formulas and are quite accurate.  You can even switch from Standard to metric units.

The other advantage is that the Calculator programs keep all of these formulas handy.  The user, who may not use them every day, can call up the program and have complete access to all of the formulas, with an explanation of the proper units and definitions. The Chassis Calculator is $95.

  Brake Calculator

3.02 for Windows 95/98, 2000, NT and XP

The Brake Calculator program performs the basic computations of hydraulic braking systems.  This begins with the geometry of the brake pedal and the force applied by the driver. Then the program calculates the forces which operate on the balance bar and master cylinder(s).  From there the forces and pressures are transmitted through the brake lines to the pistons on the calipers.  There the clamping forces are applied to the wheels and the braking force is transmitted to the tires.

The Brake Calculator allows you to design a braking system as well as investigate the effects of changing portions of the braking system.  You can compute the change in braking distribution resulting from a change in the brake balance bar or from changing a master cylinder. The Brake Calculator is $195.

Race Car Simulator

3.02 for Windows 95/98, 2000, NT and XP

This program is designed to teach the basics of vehicle dynamics.  The program uses the basic equations of vehicle dynamics and computer graphics to illustrate the effect of chassis changes on vehicle handling.  The program not only demonstrates what chassis changes will cause understeer or oversteer, but shows why the changes occur.  This learning promotes greater understanding of vehicle dynamics and a sounder knowledge of car set-up.

This program uses basic formulas of vehicle dynamics pertaining to load transfer to demonstrate the effect of chassis changes on the handling characteristics of a car.  The program uses actual values and proper equations as much as possible, but limits on vehicle data (particularly tire data) mean that this program is not a total and complete vehicle simulation.

The program teaches vehicle dynamics, explaining the effect of a spring or bar change as well as WHY.
