is proud tp represent Bill Mitchell's RACING BY THE NUMBERS™ programs. They
are intended for engineers, experienced crew members, as well as newcomers to
the sport. Over the last eighteen years the programs have been successfully used
by Formula One, Indy Car, Formula Atlantic, Winston Cup, SCCA club racers, short
track oval, autocross and Formula SAE teams. Users have included professional
engineers and design teams as well as racers new to computers. Major auto
manufacturers in the United States, Europe, Asia and Africa also use the
programs.
WinGeo3 4.0
Suspension Geometry with
Force-Based Roll Centers is a complete three-dimensional suspension
kinematic program. It Provides analysis of Double A-Arm, MacPherson Strut,
Five-Link independent, and assorted solid rear-axle suspensions. It
includes design capability that permits
the user to create a suspension with the feature desired. The Build and
Fixture features allow the user to manipulate existing parts to create a
suspension with desired characteristics. It also provides report preparation
tools. It 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. Version 3.06 now
includes force based analysis for $495.
The Premier / Data version incorporates tire squash as a result of computed load
and track data and computes 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.
The Gear Calculator program computes and displays information to assist in gear
selection. Input consists of gear ratios (either by tooth count or ratio), rear
end ratio (either by tooth count or ratio), spur gears (if any), tire size
(either diameter or circumference), and RPM shift point. With this data the
program computes and plots the relationship between RPM and MPH as well as the
RPM drop between gears. The program also produces a standard gear chart of MPH
vs. RPM. This plot shows and displays the maximum MPH in each gear (at shift
point) as well as the RPM drop between gears. The regular version includes full gearing
analysis and a bare inventory routine for $195. The advanced version adds
acceleration capability and advanced analysis incorporating torque-induced tire
slip for $395 .
