Vehicle Handling and Performance Analyser

Contact

Features

General

Recreate any vehicle using up to 64 parameters
Alter up to 56 setup adjustments and watch their effects on vehicle handling in realtime
Alter 9 parameters adjusting the current condition in which the vehicle is being analysed
Highly configurable output; all units are user selectable, all graphs axis are scalable, several graphs and many aspects of analysis can be configured
Full interoparability with the Live for Speed racing simulation
Detailed manual explaining each of the program's features

Analyse deceleration

Minimise braking distances
Export a full variable dump for the entire deceleration run to CSV for further analysis is external programs

Analyse springs (and anti-roll bars)

Adjust springs for the desired natural frequencies
Optimise roll stiffness at each end of the vehicle and the subsuequent roll balance for basic understeer/oversteer
Adjust roll and pitch angles under load

Analyse dampers

Optimise for comfort/response over bumps
Optimise for corner transient effects on roll balance

Analyse steering

Optimise static camber, caster and inclination angles for optimum camber angles under load
View effects of static toe and Ackermann steering system

Analyse drive-train

View optimal shifts points and the corresponding vehicle speed at each shift, using the current gear ratios and the engine torque curve
Optimise gear ratio spacing
Easily visualise which parts of the torque curves are used during acceleration
View some basic differential information

Analyse tyres

View vertical deformation with load and approximated contact patch area and shape
Maximise tyre traction and optimise front/rear balance for basic understeer/oversteer

Analyse aerodynamics

View vehicle theoretical top speed (given perfect gearing)
Optimise aero balance and traction balance shift with speed
View drag and lift forces created by each aero component, the total forces acting on the vehicle and how they are applied to each wheel

Analyse acceleration

Find time and distance to certain common speeds (e.g. 0-60)
Find time and speed to certain common distances (e.g. quarter mile)
Find time spent in each gear
Find peak acceleration and at what speeds traction limits acceleration
Export a full variable dump for the entire acceleration run to CSV for further analysis is external programs
Watch acceleration in real time and compare up to 2 different runs, even in different vehicles

Limitations

This program is by no means perfect and makes no claims to be. Thankfully it is not a finished product either, so these limitations will hopefully all be resolved in future versions*.
Knowing the limitations of the program is helpful in determining how accurate the information is for the vehicle being analysed.

Simplistic (linear) damper response
Dynamic camber/toe/position change with suspension movement is not modelled
Grip is not affected by camber angle
Simplistic clutch modelling

*Note: there is no set time-scale for future versions or any commitment that future versions will even be released.
